add_full

Sets a function to be called when the child indicated by pid exits, at the priority priority.

If you obtain pid from spawn_async or spawn_async_with_pipes you will need to pass g_spawn_do_not_reap_child as flag to the spawn function for the child watching to work.

In many programs, you will want to call check_wait_status in the callback to determine whether or not the child exited successfully.

Also, note that on platforms where Pid must be explicitly closed (see close_pid) pid must not be closed while the source is still active. Typically, you should invoke close_pid in the callback function for the source.

GLib supports only a single callback per process id. On POSIX platforms, the same restrictions mentioned for ChildWatchSource apply to this function.

This internally creates a main loop source using ChildWatchSource and attaches it to the main loop context using attach. You can do these steps manually if you need greater control.

Parameters:

priority	the priority of the idle source. Typically this will be in the range between g_priority_default_idle and g_priority_high_idle.
pid	process to watch. On POSIX the positive pid of a child process. On Windows a handle for a process (which doesn't have to be a child).
function	function to call
data	data to pass to function
notify	function to call when the idle is removed, or null

Returns:

the ID (greater than 0) of the event source.
