TICKIT_WATCH_LATER(3) Library Functions Manual TICKIT_WATCH_LATER(3) NAME tickit_watch_later - invoke a callback at the next round of IO events SYNOPSIS #include <tickit.h> typedef int TickitCallbackFn(Tickit *t, TickitEventflags flags, void *info, void *user); void *tickit_watch_later(Tickit *t, TickitBindFlags flags, TickitCallbackFn *fn, void *user); Link with -ltickit. DESCRIPTION tickit_watch_later() registers a callback function to be invoked by the toplevel event loop as it processes the next round of IO events. A regis- tered callback will be invoked by a running call to tickit_run(3). The callback function will be invoked once, and then destroyed afterwards. The info pointer will be NULL. When invoked, the callback function is always passed both TICKIT_EV_FIRE and TICKIT_EV_UNBIND flags to its flags argument. If the callback had been registered with the TICKIT_BIND_DESTROY flag, then it will also be invoked with the TICKIT_EV_DESTROY flag if it has not yet been invoked by the time the toplevel instance is destroyed. If registered with the TICKIT_BIND_FIRST flag, the callback will be in- serted at the start of the queue, coming before others. If not, it is ap- pended at the end. If cancelled by tickit_watch_cancel(3) the callback function is invoked with just the TICKIT_EV_UNBIND flag if it had been registered with TICKIT_BIND_UNBIND. RETURN VALUE tickit_watch_later() returns an opaque identifier pointer.
