sigpending — get
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).
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.
sigpending() function does not
currently detect any errors.
sigpending() function is defined by
IEEE Std 1003.1-2008 (“POSIX.1”).
