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.
