I am setting up a signal handler in my app like this:
void *e = signal( SIGUSR1, signal_handler );
if ( e == SIG_ERR )
...It works (i can 'kill -30 <pid>'), BUT ONLY, if I run my app outside of Xcode. When I launch it from Xcode, and I send a SIGUSR1 to my app, it always breaks at mach_msg2_trap. Obviously, this is a bit tedious for developing, since now I always have to go through Product / Archive / Distribute ... Any ideas, how I can prevent this from happening? And it's unclear to me what's going on. Can Xcode really prevent signal(3) from installing a signal handler? Or does a kill on the command line deliver the signal to several processes, one of them, maybe, an ancillary process from Xcode? Best regards, Gabriel
