In C, an empty argument list in a declaration means that the function
can accept any arguments. Use "void" instead, it means "no arguments".
C++ treats void and empty list as "no arguments".
g_tcp_accept() and g_sck_accept() should use sockadd_in6 when IPv6 is
enabled. The former code logs client IP address always "0.0.0.0" in such
case.
Fixes#412.
Conditional preprocessor directives spread throughout the code set a bad
example.
The new backport code is located in one place. The compiler checks
argument types. The backport code has no access to the caller variables.
The main code has all advantages of the new, more compact API.
Don't assume AF_INET family. Don't assume the socket is connected. Report
local address and port. Don't try to close non-sockets and invalid file
descriptors. Report errors getting socket information and closing the
socket. Use more appropriate log levels.
broken by #314. This is compatible with the fix introduced in #314.
To use non-ASCII text/filename in clipboard, chansrv needs to be run
with LC_CTYPE=*.UTF-8 because the behaviour of mbstowcs(3) function
called in chansrv depends on LC_CTYPE[1]. However #314 made
LC_CTYPE=C in chansrv context. Even if LANG and LC_* are set in
.bashrc, /etc/profile, /etc/locale.conf or something like that,
it doesn't affect in chansrv context because chansrv doesn't source
any of them unlike sesman.
So do not set LC_CTYPE to blank or "C" in g_init() in order to get
g_mbstowcs and g_wcstombs to work properly with non-ASCII UTF-8
characters in any context.
Setting LC_CTYPE to *.UTF-8 doesn't obstruct applying system
language in RHEL [2].
[1] Linux man page says:
The behavior of mbstowcs() depends on the LC_CTYPE category of
the current locale.
