Ecore version major number

Ecore version minor number

A generic callback called as a hook when a certain point in execution is reached.

A callback which is used to return data to the main function

A function which can be used to replace select() in the main loop.

A callback run for a task (timer, idler, poller, animator, etc).

This is the Ecore version information structure that can be used at runtime to detect which version of ecore is being used and adapt appropriately as follows for example:

 #if defined(ECORE_VERSION_MAJOR) && (ECORE_VERSION_MAJOR >= 1) && defined(ECORE_VERSION_MINOR) && (ECORE_VERSION_MINOR > 0)
 printf("Ecore version: %i.%i.%i\n",
        ecore_version->major,
        ecore_version->minor,
        ecore_version->micro);
 if (ecore_version->revision > 0)
   {
     printf("  Built from Git revision # %i\n", ecore_version->revision);
   }
 #endif

Resets the ecore internal state after a fork.

Ecore maintains internal data that can be affected by the fork() system call which creates a duplicate of the current process. This also duplicates file descriptors which is problematic in that these file descriptors still point to their original sources. This function makes ecore reset internal state (e.g. pipes used for signalling between threads) so they function correctly afterwards.

It is highly suggested that you call this function after any fork() system call inside the child process if you intend to use ecore features after this point and not call any exec() family functions. Not doing so will cause possible misbehaviour.

Since (EFL) :

1.7

Since :

2.3

Adds a function to be called by ecore_fork_reset().

Parameters:

func	The function to add.
data	The data to pass to this function.

This queues func to be called (and passed data as its argument) when ecore_fork_reset() is called. This allows other libraries and subsystems to also reset their internal state after a fork.

Returns:

EINA_TRUE on success, else EINA_FALSE.

Since (EFL) :

1.7

Since :

2.3

This removes the callback specified.

Parameters:

func	The function to delete.
data	The data passed to this function.

This deletes the callback added by ecore_fork_reset_callback_add() using the function and data pointer to specify which to remove.

Returns:

EINA_TRUE on success, else EINA_FALSE.

Since (EFL) :

1.7

Since :

2.3

Returns if an animator has ticked off during this loop iteration.

Returns:

EINA_TRUE if an animator has been called, EINA_FALSE otherwise.

There should be little need for anyone to use this - ever.

Since (EFL) :

Since :

3.0

Runs the application main loop.

This function will not return until ecore_main_loop_quit is called. It will check for expired timers, idlers, file descriptors being watched by fd handlers, etc. Once everything is done, before entering again on idle state, any callback set as Idle_Enterer will be called.

This function should be called once only from the same thread that initted ecore, eina etc. (ecore_init(), eina_init(), ...) and should never be nested. Never call it from within an instance of itself.

Each main loop iteration is done by calling ecore_main_loop_iterate() internally.

The polling (select) function used can be changed with ecore_main_loop_select_func_set().

The function used to check for file descriptors, events, and that has a timeout for the timers can be changed using ecore_main_loop_select_func_set().

Disables always integrating GLib.

If ecore is compiled with --with-glib=always (to always call ecore_main_loop_glib_integrate() when ecore_init() is called), then calling this before calling ecore_init() will disable the integration. This is for apps that explicitly do not want this to happen for whatever reasons they may have.

Since :

2.3

Requests ecore to integrate GLib's main loop.

This will add a small overhead during every main loop interaction by checking GLib's default main context (used by its main loop). If it have events to be checked (timers, file descriptors or idlers), then these will be polled alongside with Ecore's own events, then dispatched before Ecore's. This is done by calling ecore_main_loop_select_func_set().

This will cooperate with previously set ecore_main_loop_select_func_set() by calling the old function. Similarly, if you want to override ecore_main_loop_select_func_set() after main loop is integrated, call the new select function set by this call (get it by calling ecore_main_loop_select_func_get() right after ecore_main_loop_glib_integrate()).

This is useful to use GMainLoop libraries, like GTK, GUPnP, LibSoup, GConf and more. Adobe Flash plugin and other plugins systems depend on this as well.

Once initialized/integrated, it will be valid until Ecore is completely shut down.

Example of use:

 int main(void)
 {
    ecore_init();
    ecore_main_loop_glib_integrate();

    // some code here

    ecore_main_loop_begin();

    ecore_shutdown();

    return 0;
 }

Returns:

EINA_TRUE on success of, EINA_FALSE if it failed likely due to no GLib support in Ecore.

Note:

This is only available if Ecore was compiled with GLib support.

You don't need to call this function if Ecore was compiled with. --with-glib=always.

Since :

2.3

Runs a single iteration of the main loop to process everything on the queue.

It does everything that is already done inside an Ecore main loop, like checking for expired timers, idlers, etc. But it will do it only once and return, instead of keeping watch for new events.

DO NOT use this function unless you are the person God comes to ask for advice when He has trouble managing the Universe.

This is an extension API for ecore_main_loop_iterate() with additional parameter. It does everything that is already done inside an Ecore main loop, like checking for expired timers, idlers, etc. But it will do it only once and return, instead of keep watching for new events.

DO NOT use this function unless you are the person God comes to ask for advice when He has trouble managing the Universe.

Returns:

Gets the select function set by ecore_select_func_set(), or the native select function if none was set.

Since :

2.3

Sets the function to use when monitoring multiple file descriptors, and waiting until one of more of the file descriptors are ready for some class of I/O operation.

This function will be used instead of the system call select and could possibly be used to integrate the Ecore event loop with an external event loop.

Warning:

you don't know how to use, don't even try to use it.

Parameters:

func	The function to be used.

Since :

2.3

Calls callback asynchronously in the main loop.

Since (EFL) :

1.1.0

Parameters:

callback	The callback to call in the main loop
data	The data to give to that call back

For all calls that need to happen in the main loop (most EFL functions do), this helper function provides the infrastructure needed to do it safely by avoiding dead lock, race condition and properly wake up the main loop.

Remember after that function call, you should never touch again the data in the thread, it is owned by the main loop and your callback should take care of freeing it if necessary.

Since :

2.3

Calls callback synchronously in the main loop.

Since (EFL) :

1.1.0

Parameters:

callback	The callback to call in the main loop
data	The data to give to that call back

Returns:

The value returned by the callback in the main loop.

For all calls that need to happen in the main loop (most EFL functions do), this helper function provides the infrastructure needed to do it safely by avoiding dead lock, race condition and properly wake up the main loop.

Remember this function will block until the callback is executed in the main loop. It can take time and you have no guaranty about the timeline.

Since :

2.3

Waits for the next thread call in the main loop.

Since (EFL) :

1.13.0

Parameters:

wait	How long to wait for this callback to be called.

Note: This function should only be called in the main loop and will actually block the main loop until either a call is triggered from a thread or the time specified by wait has passed.

Since :

3.0

This function suspends the main loop in a know state.

Since (EFL) :

1.1.0

Returns:

The number of time ecore_thread_main_loop_begin() has been called in this thread, if the main loop was suspended correctly. If not, it return -1.

This function suspend the main loop in a know state, this let you use any EFL call you want after it return. Be carefully, the main loop is blocked until you call ecore_thread_main_loop_end(). This is the only sane way to achieve pseudo thread safety.

Notice that until the main loop is blocked, the thread is blocked and their is noway around that.

We still advise you, when possible, to use ecore_main_loop_thread_safe_call_async() as it will not block the thread nor the main loop.

Since :

2.3

Unlocks the main loop.

Since (EFL) :

1.1.0

Returns:

The number of time ecore_thread_main_loop_end() need to be called before the main loop is unlocked again. -1 will be returned if you are trying to unlock when there wasn't enough call to ecore_thread_main_loop_begin().

After a call to ecore_thread_main_loop_begin(), you need to absolutely call ecore_thread_main_loop_end(), or you application will stay frozen.
