SIGPENDING(2)		  FreeBSD 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.	Sig-
     nals may be pending because they are currently masked, or transiently
     before delivery (although the latter case is not normally detectable).

RETURN VALUES
     The sigpending() function returns the value 0 if successful; otherwise
     the value -1 is returned and the global variable errno is set to indicate
     the error.

ERRORS
     sigpending() will fail if:

     [EFAULT]		The set argument specified an invalid address.

SEE ALSO
     sigaction(2), sigprocmask(2)

STANDARDS
     The sigpending() function call is expected to conform to ISO/IEC
     9945-1:1990 (``POSIX.1'').
