NAME

       sigpending - Examines pending signals

SYNOPSIS

       #include <signal.h>

       int sigpending (
	       sigset_t *set );

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       sigpending(): XSH4.2

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Points to a sigset_t structure.

DESCRIPTION

       The sigpending() function stores the set of signals that are blocked from delivery and pending to the calling process in the object pointed
       to by the set parameter.

RETURN VALUES

       Upon successful completion, the sigpending() function returns a value of 0 (zero).  Otherwise, a value of -1 is returned and errno  is  set
       to indicate the error.

ERRORS

       [Tru64 UNIX]  If a bad mask parameter is passed, the calling process receives a SIGSEGV signal.

NAME

       sigpending - examine pending signals

SYNOPSIS

       #include <signal.h>

       int sigpending(sigset_t *set);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       sigpending(): _POSIX_C_SOURCE >= 1 || _XOPEN_SOURCE || _POSIX_SOURCE

DESCRIPTION

       sigpending() returns the set of signals that are pending for delivery to the calling thread (i.e., the signals which have been raised while
       blocked).  The mask of pending signals is returned in set.

RETURN VALUE

       sigpending() returns 0 on success and -1 on error.

ERRORS

       EFAULT set points to memory which is not a valid part of the process address space.

CONFORMING TO

       POSIX.1-2001.

NOTES

       See sigsetops(3) for details on manipulating signal sets.

       The set of signals that is pending for a thread is the union of the set of signals that is pending for that thread and the set  of  signals
       that is pending for the process as a whole; see signal(7).

       A child created via fork(2) initially has an empty pending signal set; the pending signal set is preserved across an execve(2).

BUGS

       In  versions of glibc up to and including 2.2.1, there is a bug in the wrapper function for sigpending() which means that information about
       pending real-time signals is not correctly returned.
