SIGPENDING(2) System Calls Manual SIGPENDING(2)

sigpendingget pending signals

#include <signal.h>

sigpending(sigset_t *set);

The () 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.

sigaction(2), sigprocmask(2), sigaddset(3)
