PTHREAD_SIGMASK(3) BSD Programmer's Manual PTHREAD_SIGMASK(3)
pthread_sigmask - examine and/or change a thread's signal mask
#include <pthread.h>
#include <signal.h>
int
pthread_sigmask(int how, const sigset_t *set, sigset_t *oset);
The pthread_sigmask() function examines and/or changes the calling
thread's signal mask.
If set is not NULL, it specifies a set of signals to be modified, and how
specifies what to set the signal mask to:
SIG_BLOCK Union of the current mask and set.
SIG_UNBLOCK Intersection of the current mask and the complement of set.
SIG_SETMASK set.
If oset is not NULL, the previous signal mask is stored in the location
pointed to by oset.
SIGKILL and SIGSTOP cannot be blocked, and will be silently ignored if
included in the signal mask.
If successful, pthread_sigmask() returns 0. Otherwise, an error is re-
turned.
pthread_sigmask() will fail if:
[EINVAL] how is not one of the defined values.
sigaction(2), sigpending(2), sigprocmask(2), sigsuspend(2), pthreads(3),
sigsetops(3)
pthread_sigmask() conforms to ISO/IEC 9945-1:1996 ("POSIX").
