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);

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 registered 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 inserted at the start of the queue,
       coming before others. If not, it is appended 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.
