sigpending —
get pending signals
#include
<signal.h>
int
sigpending(
sigset_t
*set);
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).
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.
The
sigpending() function does not currently
detect any errors.
