SIGPENDING(2)                 System Calls Manual                SIGPENDING(2)

NAME
     sigpending - get pending signals

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <signal.h>

     int
     sigpending(sigset_t *set);

DESCRIPTION
     The sigpending function returns a mask of the signals pending for
     delivery to the calling process in the location indicated by set.
     Signals may be pending because they are currently masked, or they are in
     transition before delivery (although the latter case is not normally
     detectable).

RETURN VALUES
     A 0 value indicates that the call succeeded.  A -1 return value indicates
     an error occurred and errno is set to indicate the reason.

ERRORS
     sigpending() will fail if:

     [EFAULT]           set specifies an invalid address.

SEE ALSO
     sigaction(2), sigprocmask(2), signal(7)

STANDARDS
     The sigpending function conforms to IEEE Std 1003.1-1990 ("POSIX.1").
