NAME

       tickit_watch_process - invoke a callback when a child process terminates

SYNOPSIS

       #include <tickit.h>

       typedef struct {
         pid_t pid;
         int wstatus;
       } TickitProcessWatchInfo;

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

       void *tickit_watch_process(Tickit *t, pid_t pid, TickitBindFlags flags,
           TickitCallbackFn *fn, void *user);

       Link with -ltickit.

DESCRIPTION

       tickit_watch_process()  registers  a callback function to be invoked by the toplevel event
       loop when a child process terminates. A registered callback will be invoked by  a  running
       call  to  tickit_run(3). The info pointer will point to a structure containing the process
       PID and exit status.

       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_process() returns an opaque identifier pointer.
