Hello, I have looked at a few source files for your current software. I have noticed that checks for return codes are missing. Would you like to add more error handling for return values from functions like the following? - open ? Pj_File constructor http://trac.pjsip.org/repos/browser/pjproject/trunk/pjlib/include/pj%2B%2B/file.hpp?rev=2394#L100 - pj_pool_create ? pjmedia_clock_create2 http://trac.pjsip.org/repos/browser/pjproject/trunk/pjmedia/src/pjmedia/clock_thread.c?rev=4160#L155 - fwrite ? get_frame http://trac.pjsip.org/repos/browser/pjproject/trunk/pjmedia/src/pjmedia/conference.c?rev=4198#L2041 - puts ? menu http://trac.pjsip.org/repos/browser/pjproject/trunk/pjnath/src/pjturn-client/client_main.c?rev=3553#L403 Regards, Markus
