memory leaks squashed (localtime pseudo leak is still there :-)
|
|
||||||
small improvements for OSXvnc (still not working correctly)
|
|
||||||
synced with TightVNC 1.2.3
|
|
||||||
solaris compile cleanups
|
|
||||||
many x11vnc improvements
|
|
||||||
added backchannel, an encoding which needs special clients to pass
|
|
||||||
arbitrary data to the client
|
|
||||||
changes from Tim Jansen regarding multi threading and client blocking
|
|
||||||
as well as C++ compliancy
|
|
||||||
x11vnc can be controlled by starting again with special options if compiling
|
|
||||||
with LOCAL_CONTROL defined
|
|
||||||
0.3
|
|
||||||
added x11vnc, a x0rfbserver clone
|
|
||||||
regard deferUpdateTime in processEvents, if usec<0
|
|
||||||
initialize deferUpdateTime (memory "leak"!)
|
|
||||||
changed command line handling (arguments are parsed and then removed)
|
|
||||||
added very simple example: zippy
|
|
||||||
added rfbDrawLine, rfbDrawPixel
|
|
||||||
0.2
|
|
||||||
inserted a deferUpdate mechanism (X11 independent).
|
|
||||||
removed deletion of requestedRegion
|
|
||||||
added rfbLoadConsoleFont
|
|
||||||
fixed font colour handling.
|
|
||||||
added rfbSelectBox
|
|
||||||
added rfbDrawCharWithClip to allow for clipping and a background colour.
|
|
||||||
fixed font colours
|
|
||||||
added rfbFillRect
|
|
||||||
added IO function to check password.
|
|
||||||
rfbNewClient now sets the socket in the fd_set (for the select() call)
|
|
||||||
when compiling the library with HAVE_PTHREADS and an application
|
|
||||||
which includes "rfb.h" without, the structures got mixed up.
|
|
||||||
So, the pthreads section is now always at the end, and also
|
|
||||||
you get a linker error for rfbInitServer when using two different
|
|
||||||
pthread setups.
|
|
||||||
fixed two deadlocks: when setting a cursor and when using CopyRect
|
|
||||||
fixed CopyRect when copying modified regions (they lost the modified
|
|
||||||
property)
|
|
||||||
WIN32 target compiles and works for example :-)
|
|
||||||
fixed CopyRect (was using the wrong order of rectangles...)
|
|
||||||
should also work with pthreads, because copyrects are
|
|
||||||
always sent immediately (so that two consecutive copy rects
|
|
||||||
cannot conflict).
|
|
||||||
changed rfbUndrawCursor(rfbClientPtr) to (rfbScreenInfoPtr), because
|
|
||||||
this makes more sense!
|
|
||||||
flag backgroundLoop in rfbScreenInfo (if having pthreads)
|
|
||||||
CopyRect & CopyRegion were implemented.
|
|
||||||
if you use a rfbDoCopyR* function, it copies the data in the
|
|
||||||
framebuffer. If you prefer to do that yourself, use rfbScheduleCopyR*
|
|
||||||
instead; this doesn't modify the frameBuffer.
|
|
||||||
added flag to optionally not send XCursor updates, but only RichCursor,
|
|
||||||
or if that is not possible, fall back to server side cursor.
|
|
||||||
This is useful if your cursor has many nice colours.
|
|
||||||
fixed java viewer on server side:
|
|
||||||
SendCursorUpdate would send data even before the client pixel format
|
|
||||||
was set, but the java applet doesn't like the server's format.
|
|
||||||
fixed two pthread issues:
|
|
||||||
rfbSendFramebuffer was sent by a ProcessClientMessage function
|
|
||||||
(unprotected by updateMutex).
|
|
||||||
cursor coordinates were set without protection by cursorMutex
|
|
||||||
source is now equivalent to TridiaVNC 1.2.1
|
|
||||||
pthreads now work (use iterators!)
|
|
||||||
cursors are supported (rfbSetCursor automatically undraws cursor)
|
|
||||||
support for 3 bytes/pixel (slow!)
|
|
||||||
server side colourmap support
|
|
||||||
fixed rfbCloseClient not to close the connection (pthreads!)
|
|
||||||
this is done lazily (and with proper signalling).
|
|
||||||
cleaned up mac.c (from original OSXvnc); now compiles (untested!)
|
|
||||||
compiles cleanly on Linux, IRIX, BSD, Apple (Darwin)
|
|
||||||
fixed prototypes
|
|
||||||
0.1
|
|
||||||
rewrote API to use pseudo-methods instead of required functions.
|
|
||||||
lots of clean up.
|
|
||||||
Example can show symbols now.

LibVNCServer: a library for easy implementation of a RDP/VNC server.
|
|
||||||
Copyright (C) 2001 Johannes E. Schindelin
|
|
||||||
|
|
||||||
What is it?
|
|
||||||
-----------
|
|
||||||
|
|
||||||
VNC is a set of programs using the RFB (Remote Frame Buffer) protocol. They
|
|
||||||
are designed to "export" a frame buffer via net (if you don't know VNC, I
|
|
||||||
suggest you read "Basics" below). It is already in wide use for
|
|
||||||
administration, but it is not that easy to program a server yourself.
|
|
||||||
|
|
||||||
This has been changed by LibVNCServer.
|
|
||||||
|
|
||||||
There are two examples included:
|
|
||||||
- example, a shared scribble sheet
|
|
||||||
- pnmshow, a program to show PNMs (pictures) over the net.
|
|
||||||
|
|
||||||
The examples are not too well documented, but easy straight forward and a
|
|
||||||
good starting point.
|
|
||||||
|
|
||||||
Try example: it outputs on which port it listens (default: 5900), so it is
|
|
||||||
display 0. To view, call
|
|
||||||
vncviewer :0
|
|
||||||
You should see a sheet with a gradient and "Hello World!" written on it. Try
|
|
||||||
to paint something. Note that everytime you click, there is some bigger blot.
|
|
||||||
The size depends on the mouse button you click. Open a second vncviewer with
|
|
||||||
the same parameters and watch it as you paint in the other window. This also
|
|
||||||
works over internet. You just have to know either the name or the IP of your
|
|
||||||
machine. Then it is
|
|
||||||
vncviewer machine.where.example.runs.com:0
|
|
||||||
or similar for the remote client. Now you are ready to type something. Be sure
|
|
||||||
that your mouse sits still, because everytime the mouse moves, the cursor is
|
|
||||||
reset! If you are done with that demo, just press Escape in the viewer. Note
|
|
||||||
that the server still runs, even if you closed both windows. When you
|
|
||||||
reconnect now, everything you painted and wrote is still there. So you press
|
|
||||||
"Page Up" for a blank page.
|
|
||||||
|
|
||||||
The demo pnmshow is much simpler: you either provide a filename as argument
|
|
||||||
or pipe a file through stdin. Note that the file has to be a raw pnm/ppm file,
|
|
||||||
i.e. a truecolour graphics. Only the Escape key is implemented. This may be
|
|
||||||
the best starting point if you want to learn how to use LibVNCServer. You
|
|
||||||
are confronted with the fact that the bytes per pixel can only be 8, 16 or 32.
|
|
||||||
|
|
||||||
How to use
|
|
||||||
----------
|
|
||||||
|
|
||||||
To make a server, you just have to initialise a server structure using the
|
|
||||||
function rfbDefaultScreenInit, like
|
|
||||||
rfbScreenInfoPtr rfbScreen =
|
|
||||||
rfbGetScreen(argc,argv,width,height,8,3,bpp);
|
|
||||||
where byte per pixel should be 1, 2 or 4. If performance doesn't matter,
|
|
||||||
you may try bpp=3 (internally one cannot use native data types in this
|
|
||||||
case; if you want to use this, look at pnmshow24).
|
|
||||||
|
|
||||||
|
|
||||||
You then can set hooks and io functions (see below) or other
|
|
||||||
options (see below).
|
|
||||||
|
|
||||||
And you allocate the frame buffer like this:
|
|
||||||
rfbScreen->frameBuffer = (char*)malloc(width*height*bpp);
|
|
||||||
|
|
||||||
After that, you initialize the server, like
|
|
||||||
rfbInitServer(rfbScreen);
|
|
||||||
|
|
||||||
You can use a blocking event loop, a background (pthread based) event loop,
|
|
||||||
or implement your own using the rfbProcessEvents function.
|
|
||||||
|
|
||||||
Making it interactive
|
|
||||||
---------------------
|
|
||||||
|
|
||||||
Input is handled by IO functions (see below).
|
|
||||||
|
|
||||||
Whenever you change something in the frame buffer, call rfbMarkRectAsModified.
|
|
||||||
You should make sure that the cursor is not drawn before drawing yourself
|
|
||||||
by calling rfbUndrawCursor. You can also draw the cursor using rfbDrawCursor,
|
|
||||||
but it hardly seems necessary. For cursor details, see below.
|
|
||||||
|
|
||||||
Utility functions
|
|
||||||
-----------------
|
|
||||||
|
|
||||||
Whenever you draw something, you have to call
|
|
||||||
rfbMarkRectAsModified(screen,x1,y1,x2,y2).
|
|
||||||
This tells LibVNCServer to send updates to all connected clients.
|
|
||||||
|
|
||||||
Before you draw something, be sure to call
|
|
||||||
rfbUndrawCursor(screen).
|
|
||||||
This tells LibVNCServer to hide the cursor.
|
|
||||||
Remark: There are vncviewers out there, which know a cursor encoding, so
|
|
||||||
that network traffic is low, and also the cursor doesn't need to be
|
|
||||||
drawn the cursor everytime an update is sent. LibVNCServer handles
|
|
||||||
all the details. Just set the cursor and don't bother any more.
|
|
||||||
|
|
||||||
To set the mouse coordinates (or emulate mouse clicks), call
|
|
||||||
defaultPtrAddEvent(buttonMask,x,y,cl);
|
|
||||||
However, this works only if your client doesn't do local cursor drawing. There
|
|
||||||
is no way (to my knowledge) to set the pointer of a client via RFB protocol.
|
|
||||||
IMPORTANT: do this at the end of your function, because this actually draws
|
|
||||||
the cursor if no cursor encoding is active.
|
|
||||||
|
|
||||||
What is the difference between rfbScreenInfoPtr and rfbClientPtr?
|
|
||||||
-----------------------------------------------------------------
|
|
||||||
|
|
||||||
The rfbScreenInfoPtr is a pointer to a rfbScreenInfo structure, which
|
|
||||||
holds information about the server, like pixel format, io functions,
|
|
||||||
frame buffer etc.
|
|
||||||
|
|
||||||
The rfbClientPtr is a pointer to an rfbClientRec structure, which holds
|
|
||||||
information about a client, like pixel format, socket of the
|
|
||||||
connection, etc.
|
|
||||||
|
|
||||||
A server can have several clients, but needn't have any. So, if you
|
|
||||||
have a server and three clients are connected, you have one instance
|
|
||||||
of a rfbScreenInfo and three instances of rfbClientRec's.
|
|
||||||
|
|
||||||
The rfbClientRec structure holds a member
|
|
||||||
rfbScreenInfoPtr screen
|
|
||||||
which points to the server and a member
|
|
||||||
rfbClientPtr next
|
|
||||||
to the next client.
|
|
||||||
|
|
||||||
The rfbScreenInfo structure holds a member
|
|
||||||
rfbClientPtr rfbClientHead
|
|
||||||
which points to the first client.
|
|
||||||
|
|
||||||
So, to access the server from the client structure, you use client->screen.
|
|
||||||
To access all clients from a server, get screen->rfbClientHead and
|
|
||||||
iterate using client->next.
|
|
||||||
|
|
||||||
If you change client settings, be sure to use the provided iterator
|
|
||||||
rfbGetClientIterator(rfbScreen)
|
|
||||||
with
|
|
||||||
rfbClientIteratorNext(iterator)
|
|
||||||
and
|
|
||||||
rfbReleaseClientIterator
|
|
||||||
to prevent thread clashes.
|
|
||||||
|
|
||||||
Other options
|
|
||||||
-------------
|
|
||||||
|
|
||||||
These options have to be set between rfbGetScreen and rfbInitServer.
|
|
||||||
|
|
||||||
If you already have a socket to talk to, just set rfbScreen->inetdSock
|
|
||||||
(originally this is for inetd handling, but why not use it for your purpose?).
|
|
||||||
|
|
||||||
To also start an HTTP server (running on port 5800+display_number), you have
|
|
||||||
to set rfbScreen->httpdDir to a directory containing vncviewer.jar and
|
|
||||||
index.vnc (like the included "classes" directory).
|
|
||||||
|
|
||||||
Hooks and IO functions
|
|
||||||
----------------------
|
|
||||||
|
|
||||||
There exist the following IO functions as members of rfbScreen:
|
|
||||||
kbdAddEvent, kbdReleaseAllKeys, ptrAddEvent and setXCutText
|
|
||||||
|
|
||||||
kbdAddEvent(Bool down,KeySym key,rfbClientPtr cl)
|
|
||||||
is called when a key is pressed.
|
|
||||||
kbdReleaseAllKeys(rfbClientPtr cl)
|
|
||||||
is not called at all (maybe in the future).
|
|
||||||
ptrAddEvent(int buttonMask,int x,int y,rfbClientPtr cl)
|
|
||||||
is called when the mouse moves or a button is pressed.
|
|
||||||
WARNING: if you want to have proper cursor handling, call
|
|
||||||
defaultPtrAddEvent(buttonMask,x,y,cl)
|
|
||||||
in your own function. This sets the coordinates of the cursor.
|
|
||||||
setXCutText(char* str,int len,rfbClientPtr cl)
|
|
||||||
is called when the selection changes.
|
|
||||||
|
|
||||||
There are only two hooks:
|
|
||||||
newClientHook(rfbClientPtr cl)
|
|
||||||
is called when a new client has connected.
|
|
||||||
displayHook
|
|
||||||
is called just before a frame buffer update is sent.
|
|
||||||
|
|
||||||
You can also override the following methods:
|
|
||||||
getCursorPtr(rfbClientPtr cl)
|
|
||||||
This could be used to make an animated cursor (if you really want ...)
|
|
||||||
setTranslateFunction(rfbClientPtr cl)
|
|
||||||
If you insist on colour maps or something more obscure, you have to
|
|
||||||
implement this. Default is a trueColour mapping.
|
|
||||||
|
|
||||||
Cursor handling
|
|
||||||
---------------
|
|
||||||
|
|
||||||
The screen holds a pointer
|
|
||||||
rfbCursorPtr cursor
|
|
||||||
to the current cursor. Whenever you set it, remember that any dynamically
|
|
||||||
created cursor (like return value from rfbMakeXCursor) is not free'd!
|
|
||||||
|
|
||||||
The rfbCursor structure consists mainly of a mask and a source. The mask
|
|
||||||
describes, which pixels are drawn for the cursor (a cursor needn't be
|
|
||||||
rectangular). The source describes, which colour those pixels should have.
|
|
||||||
|
|
||||||
The standard is an XCursor: a cursor with a foreground and a background
|
|
||||||
colour (stored in backRed,backGreen,backBlue and the same for foreground
|
|
||||||
in a range from 0-0xffff). Therefore, the arrays "mask" and "source"
|
|
||||||
contain pixels as single bits stored in bytes in MSB order. The rows are
|
|
||||||
padded, such that each row begins with a new byte (i.e. a 10x4
|
|
||||||
cursor's mask has 2x4 bytes, because 2 bytes are needed to hold 10 bits).
|
|
||||||
|
|
||||||
It is however very easy to make a cursor like this:
|
|
||||||
|
|
||||||
char* cur=" "
|
|
||||||
" xx "
|
|
||||||
" x "
|
|
||||||
" ";
|
|
||||||
char* mask="xxxx"
|
|
||||||
"xxxx"
|
|
||||||
"xxxx"
|
|
||||||
"xxx ";
|
|
||||||
rfbCursorPtr c=rfbMakeXCursor(4,4,cur,mask);
|
|
||||||
|
|
||||||
You can even set "mask" to NULL in this call and LibVNCServer will calculate
|
|
||||||
a mask for you (dynamically, so you have to free it yourself).
|
|
||||||
|
|
||||||
There is also an array named "richSource" for colourful cursors. They have
|
|
||||||
the same format as the frameBuffer (i.e. if the server is 32 bit,
|
|
||||||
a 10x4 cursor has 4x10x4 bytes).
|
|
||||||
|
|
||||||
History
|
|
||||||
-------
|
|
||||||
|
|
||||||
LibVNCServer is based on Tridia VNC and OSXvnc, which in turn are based on
|
|
||||||
the original code from ORL/AT&T.
|
|
||||||
|
|
||||||
When I began hacking with computers, my first interest was speed. So, when I
|
|
||||||
got around assembler, I programmed the floppy to do much of the work, because
|
|
||||||
it's clock rate was higher than that of my C64. This was my first experience
|
|
||||||
with client/server techniques.
|
|
||||||
|
|
||||||
When I came around Xwindows (much later), I was at once intrigued by the
|
|
||||||
elegance of such connectedness between the different computers. I used it
|
|
||||||
a lot - not the least priority lay on games. However, when I tried it over
|
|
||||||
modem from home, it was no longer that much fun.
|
|
||||||
|
|
||||||
When I started working with ASP (Application Service Provider) programs, I
|
|
||||||
tumbled across Tarantella and Citrix. Being a security fanatic, the idea of
|
|
||||||
running a server on windows didn't appeal to me, so Citrix went down the
|
|
||||||
basket. However, Tarantella has it's own problems (security as well as the
|
|
||||||
high price). But at the same time somebody told me about this "great little
|
|
||||||
administrator's tool" named VNC. Being used to windows programs' sizes, the
|
|
||||||
surprise was reciprocal inverse to the size of VNC!
|
|
||||||
|
|
||||||
At the same time, the program "rdesktop" (a native Linux client for the
|
|
||||||
Terminal Services of Windows servers) came to my attention. There where even
|
|
||||||
works under way to make a protocol converter "rdp2vnc" out of this. However,
|
|
||||||
my primary goal was a slow connection and rdp2vnc could only speak RRE
|
|
||||||
encoding, which is not that funny with just 5kB/s. Tim Edmonds, the original
|
|
||||||
author of rdp2vnc, suggested that I adapt it to Hextile Encoding, which is
|
|
||||||
better. I first tried that, but had no success at all (crunchy pictures).
|
|
||||||
|
|
||||||
Also, I liked the idea of an HTTP server included and possibly other
|
|
||||||
encodings like the Tight Encodings from Const Kaplinsky. So I started looking
|
|
||||||
for libraries implementing a VNC server where I could steal what I can't make.
|
|
||||||
I found some programs based on the demo server from AT&T, which was also the
|
|
||||||
basis for rdp2vnc (can only speak Raw and RRE encoding). There were some
|
|
||||||
rumors that GGI has a VNC backend, but I didn't find any code, so probably
|
|
||||||
there wasn't a working version anyway.
|
|
||||||
|
|
||||||
All of a sudden, everything changed: I read on freshmeat that "OSXvnc" was
|
|
||||||
released. I looked at the code and it was not much of a problem to work out
|
|
||||||
a simple server - using every functionality there is in Xvnc. It became clear
|
|
||||||
to me that I *had* to build a library out of it, so everybody can use it.
|
|
||||||
Every change, every new feature can propagate to every user of it.
|
|
||||||
|
|
||||||
It also makes everything easier:
|
|
||||||
You don't care about the cursor, once set (or use the standard cursor).
|
|
||||||
You don't care about those sockets. You don't care about encodings.
|
|
||||||
You just change your frame buffer and inform the library about it. Every once
|
|
||||||
in a while you call rfbProcessEvents and that's it.
|
|
||||||
|
|
||||||
Basics
|
|
||||||
------
|
|
||||||
|
|
||||||
VNC (Virtual network computing) works like this: You set up a server and can
|
|
||||||
connect to it via vncviewers. The communication uses a protocol named RFB
|
|
||||||
(Remote Frame Buffer). If the server supports HTTP, you can also connect
|
|
||||||
using a java enabled browser. In this case, the server sends back a
|
|
||||||
vncviewer applet with the correct settings.
|
|
||||||
|
|
||||||
There exist several encodings for VNC, which are used to compress the regions
|
|
||||||
which have changed before they are sent to the client. A client need not be
|
|
||||||
able to understand every encoding, but at least Raw encoding. Which encoding
|
|
||||||
it understands is negotiated by the RFB protocol.
|
|
||||||
|
|
||||||
The following encodings are known to me:
|
|
||||||
Raw, RRE, CoRRE, Hextile, CopyRect from the original AT&T code and
|
|
||||||
Tight, ZLib, LastRect, XCursor, RichCursor from Const Kaplinsky et al.
|
|
||||||
|
|
||||||
If you are using a modem, you want to try the "new" encodings. Especially
|
|
||||||
with my 56k modem I like ZLib or Tight with Quality 0. In my tests, it even
|
|
||||||
beats Tarantella.
|
|
||||||
|
|
||||||
There is the possibility to set a password, which is also negotiated by the
|
|
||||||
RFB protocol, but IT IS NOT SECURE. Anybody sniffing your net can get the
|
|
||||||
password. You really should tunnel through SSH.
|
|
||||||
|
|
||||||
Windows or: why do you do that to me?
|
|
||||||
--------------------------------------------
|
|
||||||
|
|
||||||
If you love products from Redmod, you better skip this paragraph.
|
|
||||||
I am always amazed how people react whenever Microsoft(tm) puts in some
|
|
||||||
features into their products which were around for a long time. Especially
|
|
||||||
reporters seem to not know dick about what they are reporting about! But
|
|
||||||
what is everytime annoying again, is that they don't do it right. Every
|
|
||||||
concept has it's new name (remember what enumerators used to be until
|
|
||||||
Mickeysoft(tm) claimed that enumerators are what we thought were iterators.
|
|
||||||
Yeah right, enumerators are also containers. They are not separate. Muddy.)
|
|
||||||
|
|
||||||
There are three packages you want to get hold of: zlib, jpeg and pthreads.
|
|
||||||
The latter is not strictly necessary, but when you put something like this
|
|
||||||
into your source:
|
|
||||||
|
|
||||||
#define MUTEX(s)
|
|
||||||
struct {
|
|
||||||
int something;
|
|
||||||
MUTEX(latex);
|
|
||||||
}
|
|
||||||
|
|
||||||
Microsoft's C++ compiler doesn't do it. It complains that this is an error.
|
|
||||||
|
|
||||||
You can find the packages at
|
|
||||||
http://www.gimp.org/win32/extralibs-dev-20001007.zip
|
|
||||||
|
|
||||||
Thanks go to all the GIMP team!
|
|
||||||
|
|
||||||
What are those other targets in the Makefile?
|
|
||||||
---------------------------------------------
|
|
||||||
|
|
||||||
OSXvnc-server is the original OSXvnc adapted to use the library, which was in
|
|
||||||
turn adapted from OSXvnc. As you easily can see, the OSX dependend part is
|
|
||||||
minimal.
|
|
||||||
|
|
||||||
storepasswd is the original program to save a vnc style password in a file.
|
|
||||||
Unfortunately, authentication as every vncviewer speaks it means the server
|
|
||||||
has to know the plain password. You really should tunnel via ssh or use
|
|
||||||
your own PasswordCheck to build a PIN/TAN system.
|
|
||||||
|
|
||||||
sratest is a test unit. Run it to assert correct behaviour of sraRegion. I
|
|
||||||
wrote this to test my iterator implementation.
|
|
||||||
|
|
||||||
blooptest is a test of pthreads. It is just the example, but with a background
|
|
||||||
loop to hunt down thread lockups.
|
|
||||||
|
|
||||||
pnmshow24 is like pnmshow, but it uses 3 bytes/pixel internally, which is not
|
|
||||||
as efficient as 4 bytes/pixel for translation, because there is no native data
|
|
||||||
type of that size, so you have to memcpy pixels and be real cautious with
|
|
||||||
endianness. Anyway, it works.
|
|
||||||
|
|
||||||
fontsel is a test for rfbSelectBox and rfbLoadConsoleFont. If you have Linux
|
|
||||||
console fonts, you can browse them via VNC. Directory browsing not implemented
|
|
||||||
yet :-(
|
|
||||||
|
|
||||||
Why I don't feel bad about GPL
|
|
||||||
------------------------------
|
|
||||||
|
|
||||||
At the beginning of this projects I would have liked to make it a BSD
|
|
||||||
license. However, it is based on plenty of GPL'ed code, so it has to be
|
|
||||||
a GPL. I hear BeeGee complaining: "but that's invasive, every derivative
|
|
||||||
work, even just linking, makes my software GPL!"
|
|
||||||
|
|
||||||
Yeah. That's right. It is because there are nasty jarheads out there who
|
|
||||||
would take anybody's work and claim it their own, selling it for much too
|
|
||||||
much money, stealing freedom and innovation from others, saying they were
|
|
||||||
the maintainers of innovation, lying, making money with that.
|
|
||||||
|
|
||||||
The people at AT&T worked really well to produce something as clean and lean
|
|
||||||
as VNC. The managers decided that for their fame, they would release the
|
|
||||||
program for free. But not only that! They realized that by releasing also
|
|
||||||
the code for free, VNC would become an evolving little child, conquering
|
|
||||||
new worlds, making it's parents very proud. As well they can be! To protect
|
|
||||||
this innovation, they decided to make it GPL, not BSD. The principal
|
|
||||||
difference is: You can make closed source programs deriving from BSD, not
|
|
||||||
from GPL. You have to give proper credit with both.
|
|
||||||
|
|
||||||
Now, why not BSD? Well, imagine your child being some famous actor. Along
|
|
||||||
comes a manager who exploits your child exclusively, that is: nobody else
|
|
||||||
can profit from the child, it itself included. Got it?
|
|
||||||
|
|
||||||
What reason do you have now to use this library commercially?
|
|
||||||
|
|
||||||
Several: You don't have to give away your product. Then you have effectively
|
|
||||||
circumvented the GPL, because you have the benefits of other's work and you
|
|
||||||
don't give back anything and you will be in hell for that. In fact, this
|
|
||||||
library, as my other projects, is a payback for all the free software I can
|
|
||||||
use (and sometimes, make better). For example, just now, I am using XEmacs
|
|
||||||
on top X11, all running under Linux.
|
|
||||||
|
|
||||||
Better: Use a concept like MySQL. This is free software, however, they make
|
|
||||||
money with it. If you want something implemented, you have the choice:
|
|
||||||
Ask them to do it (and pay a fair price), or do it yourself, normally giving
|
|
||||||
back your enhancements to the free world of computing.
|
|
||||||
|
|
||||||
Learn from it: If you like the style this is written, learn how to imitate
|
|
||||||
it. If you don't like the style, learn how to avoid those things you don't
|
|
||||||
like. I learnt so much, just from looking at code like Linux, XEmacs,
|
|
||||||
LilyPond, STL, etc.

/* The following two members are used to minimise the amount of unnecessary
|
|
||||||
drawing caused by cursor movement. Whenever any drawing affects the
|
|
||||||
part of the screen where the cursor is, the cursor is removed first and
|
|
||||||
then the drawing is done (this is what the sprite routines test for).
|
|
||||||
Afterwards, however, we do not replace the cursor, even when the cursor
|
|
||||||
is logically being moved across the screen. We only draw the cursor
|
|
||||||
again just as we are about to send the client a framebuffer update.
|
|
||||||
|
|
||||||
We need to be careful when removing and drawing the cursor because of
|
|
||||||
their relationship with the normal drawing routines. The drawing
|
|
||||||
routines can invoke the cursor routines, but also the cursor routines
|
|
||||||
themselves end up invoking drawing routines.
|
|
||||||
|
|
||||||
Removing the cursor (rfbUndrawCursor) is eventually achieved by
|
|
||||||
doing a CopyArea from a pixmap to the screen, where the pixmap contains
|
|
||||||
the saved contents of the screen under the cursor. Before doing this,
|
|
||||||
however, we set cursorIsDrawn to FALSE. Then, when CopyArea is called,
|
|
||||||
it sees that cursorIsDrawn is FALSE and so doesn't feel the need to
|
|
||||||
(recursively!) remove the cursor before doing it.
|
|
||||||
|
|
||||||
Putting up the cursor (rfbDrawCursor) involves a call to
|
|
||||||
PushPixels. While this is happening, cursorIsDrawn must be FALSE so
|
|
||||||
that PushPixels doesn't think it has to remove the cursor first.
|
|
||||||
Obviously cursorIsDrawn is set to TRUE afterwards.
|
|
||||||
|
|
||||||
Another problem we face is that drawing routines sometimes cause a
|
|
||||||
framebuffer update to be sent to the RFB client. When the RFB client is
|
|
||||||
already waiting for a framebuffer update and some drawing to the
|
|
||||||
framebuffer then happens, the drawing routine sees that the client is
|
|
||||||
ready, so it calls rfbSendFramebufferUpdate. If the cursor is not drawn
|
|
||||||
at this stage, it must be put up, and so rfbSpriteRestoreCursor is
|
|
||||||
called. However, if the original drawing routine was actually called
|
|
||||||
from within rfbSpriteRestoreCursor or rfbSpriteRemoveCursor we don't
|
|
||||||
want this to happen. So both the cursor routines set
|
|
||||||
dontSendFramebufferUpdate to TRUE, and all the drawing routines check
|
|
||||||
this before calling rfbSendFramebufferUpdate. */

* sockets.c - deal with TCP & UDP sockets.
|
|
||||||
*
|
|
||||||
* This code should be independent of any changes in the RFB protocol. It just
|
|
||||||
* deals with the X server scheduling stuff, calling rfbNewClientConnection and
|
|
||||||
* rfbProcessClientMessage to actually deal with the protocol. If a socket
|
|
||||||
* needs to be closed for any reason then rfbCloseClient should be called, and
|
|
||||||
* this in turn will call rfbClientConnectionGone. To make an active
|
|
||||||
* connection out, call rfbConnect - note that this does _not_ call
|
|
||||||
* rfbNewClientConnection.
|
|
||||||
*
|
|
||||||
* This file is divided into two types of function. Those beginning with
|
|
||||||
* "rfb" are specific to sockets using the RFB protocol. Those without the
|
|
||||||
* "rfb" prefix are more general socket routines (which are used by the http
|
|
||||||
* code).
|
|
||||||
*

|
|
||||||
* not EWOULDBLOCK.
