* Example of initializing and shutting down Evas.
* For this introduction to Evas, we'll simply turn it on and off and
* explain everything we're doing from the absolute basics, to provide
* a starting point for understanding the other examples in this set,
* which won't be explaining things quite so verbosely.
* See the @ref Example_Evas_Buffer_Simple as the next step in the tutorial.
* Evas examples can be built using the regular `make examples`, but each
* example includes the compiler line for building that specific example if
* you wish to build it in isolation:
* gcc -o evas-init-shutdown evas-init-shutdown.c `pkg-config --libs --cflags evas`
* For this compilation to function properly, you'll need to have built and
* installed the evas library and include files in a location that the pkg-config
* tool will be able to find. The example executable will be 'evas-init-shutdown'.
Eina_List *engine_list, *l;
/* Initialize Evas. This will startup other dependencies such as
* eina, eet, ecore, etc. and initializes various internal things
* (threads, filters, etc.) */
/* When building Evas you can configure a variety of engines to be
* built with it. Get a list of what engines are available using the
* evas_render_method_list routine.
engine_list = evas_render_method_list();
fprintf(stderr, "ERROR: Evas supports no engines! Exit.\n");
/* 'engine_list' is a linked list (@see Eina_List.) The
* EINA_LIST_FOREACH macro permits navigating through the items using
* the iterator 'l', making the node data available as 'engine_name'.
printf("Available Evas Engines:\n");
EINA_LIST_FOREACH(engine_list, l, engine_name)
/* To free the list, we use evas_render_method_list's corresponding
* destructor routine.
/* Shuts down all dependencies if nothing else is using them, and
* clears allocated data held internally.
