sigpending -- get pending signals
Standard C Library (libc, -lc)
The sigpending function returns a mask of the signals pending for deliv-
ery to the calling process in the location indicated by set. Signals may
be pending because they are currently masked, or they are in transition
before delivery (although the latter case is not normally detectable).
A 0 value indicates that the call succeeded. A -1 return value indicates
an error occurred and errno is set to indicate the reason.
sigpending() will fail if:
[EFAULT] set specifies an invalid address.
sigaction(2), sigprocmask(2), signal(7)
The sigpending function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
