If func_free is NULL, then ecore's generic event free function is used. This is OK as long as your event struct does not contain any dynamically allocated data such as strings etc., which would cause memory leaks. So the rule is if you have a pointer to malloc'ed data like a string or a struct, you write your own free function that will make sure those pointers are freed before freeing the event itself. -- Ibukun Olumuyiwa http://xcomputerman.com "God is dead." - Nietzche "Nietzche is dead." - God ------------------------------------------------------- This SF.Net email is sponsored by Sleepycat Software Learn developer strategies Cisco, Motorola, Ericsson & Lucent use to deliver higher performing products faster, at low TCO. http://www.sleepycat.com/telcomwpreg.php?From=osdnemail3 _______________________________________________ enlightenment-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/enlightenment-devel
