TICKIT_WATCH_TIMER_AFTER_MSEC (3)

NAME

tickit_watch_timer_after_* - invoke a callback after a fixed delay

SYNOPSIS

#include <tickit.h> 
typedef int TickitCallbackFn(Tickit *t, TickitEventflags flags,
    void *info, void *user); 
void *tickit_timer_after_msec(Tickit *t, int msec,
    TickitBindFlags flags, TickitCallbackFn *fn, void *user);
void *tickit_timer_after_tv(Tickit *t, const struct timeval *after,
    TickitBindFlags flags, TickitCallbackFn *fn, void *user);

DESCRIPTION

The tickit_watch_timer_after_*() family of functions register a callback function to be invoked by the toplevel event loop a fixed delay afterwards. 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.

RETURN VALUE

tickit_timer_after_msec() and tickit_timer_after_tv() return an opaque identifier pointer.
