tickit_watch_timer_at_epoch - Man Page

invoke a callback at a fixed future time


#include <tickit.h>

typedef int TickitCallbackFn(Tickit *t, TickitEventflags flags,
    void *info, void *user);

void *tickit_watch_timer_at_epoch(Tickit *t, time_t at,
    TickitBindFlags flags, TickitCallbackFn *fn, void *user);
void *tickit_watch_timer_at_tv(Tickit *t, const struct timeval *at,
    TickitBindFlags flags, TickitCallbackFn *fn, void *user);

The tickit_watch_timer_at_*() family of functions register a callback function to be invoked by the toplevel event loop at a fixed time in the future. A registered callback will be invoked by a running call to tickit_run(3). The callback function will be invoked once, and then destroyed afterwards. Each function returns an opaque pointer value which serves to identify this instance. 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 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_timer_at_epoch() and tickit_watch_timer_at_tv() return an opaque identifier pointer.
