#### Declaration

    gboolean
    (* GSourceFuncsDispatchFunc) (

    )

#### Description [src]

Dispatches the source callback.

Called to dispatch the event source, after it has returned `TRUE` in either its prepare or its check function, or if a ready time has been reached. The dispatch function receives a callback function and user data. The callback function may be `NULL` if the source was never connected to a callback using `g_source_set_callback()`. The dispatch function should call the callback function with `user_data` and whatever additional parameters are needed for this type of event source. The return value of the dispatch function should be `G_SOURCE_REMOVE` if the source should be removed or `G_SOURCE_CONTINUE` to keep it.
