SYNOPSIS
#include <signal.h>

sigpending(sigset_t *set);
DESCRIPTION

delivery to the calling process in the location indicated by set. Sig‐
nals 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 indicate
the error.
ERRORSsigpending() will fail if:
[EFAULT] The set argument specified an invalid address.

The sigpending() function call is expected to conform to ISO/IEC
9945-1:1990 (“POSIX.1”).
