/**
|
|
* @file Ecore.h
|
|
* @brief The file that provides the program utility, main loop and timer
|
|
* functions.
|
|
*
|
|
* This header provides the Ecore event handling loop. For more
|
|
* details, see @ref Ecore_Main_Loop_Group.
|
|
*
|
|
* For the main loop to be of any use, you need to be able to add events
|
|
* and event handlers.
|
|
*
|
|
* There is also provision for callbacks for when the loop enters or
|
|
* exits an idle state. See @ref Idle_Group for more information.
|
|
*
|
|
* Functions are also provided for spawning child processes using fork.
|
|
* See @ref Ecore_Exe_Basic_Group and @ref Ecore_Exe_Signal_Group for
|
|
* more details.
