Rich Felker	40bd1726b6	remove implementation-reserved bits when saving signal mask ... this fix is necessary because a program could be started with some of the implementation-reserved signals masked (e.g. due to exec having been called from a signal handler, or from a non-musl program) and then could obtain an invalid-to-use-later sigset_t as the old/saved signal mask.	2012-06-02 20:04:27 -04:00
Rich Felker	ad5881842e	clean up pthread_sigmask/sigprocmask dependency order ... it's nicer for the function that doesn't use errno to be independent, and have the other one call it. saves some time and avoids clobbering errno.	2011-07-30 21:09:14 -04:00
Rich Felker	500c969f05	fix error handling for pthread_sigmask ... it must return errno, not -1, and should reject invalud values for how.	2011-03-09 20:31:06 -05:00
