NAME    [Toc]    [Back]

     sigpending -- get pending signals

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <signal.h>

     sigpending(sigset_t *set);

DESCRIPTION    [Toc]    [Back]

     The sigpending() system call 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 transiently
     before delivery (although the latter case is not normally detectable).

RETURN VALUES    [Toc]    [Back]

     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    [Toc]    [Back]

     The sigpending() system call will fail if:

     [EFAULT]		The set argument specified an invalid address.

SEE ALSO    [Toc]    [Back]

     sigaction(2), sigprocmask(2), sigsuspend(2), sigsetops(3)

STANDARDS    [Toc]    [Back]

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