NAME

     sigpending -- get pending signals

SYNOPSIS

     #include <signal.h>

     int
     sigpending(sigset_t *set);

DESCRIPTION

     The sigpending function 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

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

ERRORS

     The sigpending function does not currently detect any errors.

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 indi-
     cate the error.

ERRORS

     The sigpending() system call will fail if:

     [EFAULT]		The set argument specified an invalid address.

SEE ALSO

STANDARDS

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