SIGPENDING(2)             NetBSD 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 deliv-
     ery to the calling process in the location indicated by set.  Signals may
     be pending because they are currently masked, or they are in transition
     before delivery (although the latter case is not normally detectable).


RETURN VALUES

     A 0 value indicates that the call succeeded.  A -1 return value indicates
     an error occurred and errno is set to indicate the reason.


ERRORS

     sigpending() will fail if:

     [EFAULT]           set specifies an invalid address.


SEE ALSO

     sigaction(2), sigprocmask(2), signal(7)


STANDARDS

     The sigpending function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
