sigwait

SIGWAIT(2)						      BSD System Calls Manual							SIGWAIT(2)

NAME

     sigwait -- select a set of signals

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <signal.h>

     int
     sigwait(const sigset_t * restrict set, int * restrict sig);

DESCRIPTION

     The sigwait() system call selects a set of signals, specified by set.  If none of the selected signals are pending, sigwait() waits until one
     or more of the selected signals has been generated.  Then sigwait() atomically clears one of the selected signals from the set of pending
     signals for the process and sets the location pointed to by sig to the signal number that was cleared.

     The signals specified by set should be blocked at the time of the call to sigwait().

     If more than one thread is using sigwait() to wait for the same signal, no more than one of these threads will return from sigwait() with the
     signal number.  If more than a single thread is blocked in sigwait() for a signal when that signal is generated for the process, it is
     unspecified which of the waiting threads returns from sigwait().  If the signal is generated for a specific thread, as by pthread_kill(),
     only that thread will return.

     Should any of the multiple pending signals in the range SIGRTMIN to SIGRTMAX be selected, it will be the lowest numbered one.  The selection
     order between realtime and non-realtime signals, or between multiple pending non-realtime signals, is unspecified.

RETURN VALUES

     If successful, sigwait() returns 0 and sets the location pointed to by sig to the cleared signal number.  Otherwise, an error number is
     returned.

ERRORS

     The sigwait() system call will fail if:

     [EINVAL]		The set argument specifies one or more invalid signal numbers.

     [EFAULT]		Any arguments point outside the allocated address space or there is a memory protection fault.

SEE ALSO

     sigaction(2), sigpending(2), sigqueue(2), sigsuspend(2), sigtimedwait(2), sigwaitinfo(2), pause(3), pthread_sigmask(3)

STANDARDS

     The sigwait() function conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').
