|
||
* timeout and the source also has a ready time set, then the
|
||
* lower of the two will be used.
|

|
||
* be %NULL, in which case the effect is as if the function always returns
|
||
* %FALSE.
|
||
* @dispatch: 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.
|
||
* @finalize: Called when the source is finalized. At this point, the source
|
||
* will have been destroyed, had its callback cleared, and have been removed
|
||
* from its #GMainContext, but it will still have its final reference count,
|

*
|
||
* The `GSourceFuncs` struct contains a table of
|
||
* functions used to handle event sources in a generic manner.
|
||
*
|
||
* For idle sources, the prepare and check functions always return %TRUE
|
||
* to indicate that the source is always ready to be processed. The prepare
|
||
* function also returns a timeout value of 0 to ensure that the poll() call
|
||
* doesn't block (since that would be time wasted which could have been spent
|
||
* running the idle function).
|
||
*
|
||
* For timeout sources, the prepare and check functions both return %TRUE
|
||
* if the timeout interval has expired. The prepare function also returns
|
||
* a timeout value to ensure that the poll() call doesn't block too long
|
||
* and miss the next timeout.
|
||
*
|
||
* For file descriptor sources, the prepare function typically returns %FALSE,
|
||
* since it must wait until poll() has been called before it knows whether
|
||
* any events need to be processed. It sets the returned timeout to -1 to
|
||
* indicate that it doesn't mind how long the poll() call blocks. In the
|
||
* check function, it tests the results of the poll() call to see if the

* required condition has been met, and returns %TRUE if so.
