NAME

       sigpending — get pending signals

LIBRARY

       Standard C Library (libc, -lc)

SYNOPSIS

       #include <signal.h>

       int
       sigpending(sigset_t *set);

DESCRIPTION

       The  sigpending() system call returns a mask of the signals pending for delivery to the calling thread or
       the calling process in the location indicated by set.  Signals 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

       The sigpending() system call will fail if:

       [EFAULT]           The set argument specified an invalid address.

STANDARDS

       The sigpending() system call is expected to conform to ISO/IEC 9945-1:1990 (“POSIX.1”).
