NAME
sigpending -- get pending signals
LIBRARY

SYNOPSIS
#include <signal.h>
int
sigpending(sigset_t *set);

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.
