/* To use this file with libraries the following macros are useful:
|
||
|
|
|
||
|
|
#define _ASSUAN_EXT_SYM_PREFIX _foo_
|
||
|
|
|
||
|
|
This prefixes all external symbols with "_foo_".
|
||
|
|
|
||
|
|
#define _ASSUAN_ONLY_GPG_ERRORS
|
||
|
|
|
||
|
|
If this is defined all old-style Assuan error codes are made
|
||
|
|
inactive as well as other dereacted stuff.
|
||
|
|
|
||
|
|
The follwing macros are used internally in the implementation of
|
||
|
|
libassuan:
|
||
|
|
|
||
|
|
#define _ASSUAN_NO_PTH
|
||
|
|
|
||
|
|
This avoids inclusion of special GNU Pth hacks.
|
||
|
|
|
||
|
|
#define _ASSUAN_NO_FIXED_SIGNALS
|
||
|
|
|
||
|
|
This disables changing of certain signal handler; i.e. SIGPIPE.
|
||
|
|
|
||
|
|
#define _ASSUAN_USE_DOUBLE_FORK
|
||
|
|
|
||
|
|
Use a double fork approach when connecting to a server through
|
||
|
|
a pipe.
