Removes the specified signal number from the set of signals being monitored by a signal handler.

inline |
|
inlinestatic |
Cancels the specified signal wait operation if it is pending.
The completion task is submitted for execution with signo = 0.
|
inlinestatic |
Aborts the specified signal wait operation if it is pending.
If aborted, the completion task is not submitted for execution.
ev_future_t * io_sigset_async_wait | ( | io_sigset_t * | sigset, |
ev_exec_t * | exec, | ||
struct io_sigset_wait ** | pwait | ||
) |
Submits an asynchronous wait operation to a signal handler and creates a future which becomes ready once the wait operation completes (or is canceled).
The result of the future is an int
containing the signal number, or 0 if the wait operation was canceled.
sigset | a pointer to a signal handler. |
exec | a pointer to the executor used to execute the completion function of the wait operation. If NULL, the default executor of the signal handler is used. |
pwait | the address at which to store a pointer to the wait operation (can be NULL). |
