Changeset 3986 for pjproject/branches/1.x/pjlib/src/pj/os_core_symbian.cpp

Message:

Close #1466 (using PJLIB outside PJSUA-LIB context):

• static reference counter for PJLIB init/shutdown.
• implemented atexit() in PJMEDIA and PJSIP level: pjmedia_endpt_atexit() & pjsip_endpt_atexit().
• updated pjmedia/transport_srtp.c, pjsip/sip_timer.c, and pjsip/sip_replaces.c to use the new atexit() functions.
• API change: pjmedia_srtp_init_lib() now requires 'pjmedia_endpt' param.
