TICKIT_WATCH_PROCESS(3) Library Functions Manual TICKIT_WATCH_PROCESS(3) 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 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_process() returns an opaque identifier pointer.
