NAME
sigpending —
get pending signals
SYNOPSIS
#include
<signal.h>
int
sigpending(sigset_t

DESCRIPTION

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
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
ERRORS
The sigpending function does not currently
detect any errors.
