SIGPENDING(2) FreeBSD System Calls Manual SIGPENDING(2)
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
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.
