PROLOG

NAME

       sigpending - examine pending signals

SYNOPSIS

       #include <signal.h>

       int sigpending(sigset_t *set);

DESCRIPTION

       The sigpending() function shall store, in the location referenced by the set argument, the set of signals that are blocked from delivery to
       the calling thread and that are pending on the process or the calling thread.

RETURN VALUE

       Upon successful completion, sigpending() shall return 0; otherwise, -1 shall be returned and errno set to indicate the error.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
