annotate include/freeDiameter/libfdproto.h @ 658:f198d16fa7f4
Initial commit for 1.1.0:
* Restructuring:
* libfreeDiameter:
- renamed folder & binary into libfdproto
- renamed libfD.h into fdproto-internal.h
- removed signals management (replaced by triggers in libfdcore)
* freeDiameter split into:
- libfdcore (most contents)
- renamed fD.h into fdcore-internal.h
- added core.c for framework init/shutdown.
- new triggers mechanism in events.c.
- freeDiameterd (main, command line parsing, signals management)
* tests:
- now in top-level directory tests.
* other changes:
- fd_dict_new now returns 0 on duplicate identical entries.
- fixes in dict_legacy_xml
- fixes in some dictionaries
- moved FD_DEFAULT_CONF_FILENAME definition to freeDiameter-host.h
