This example shows how an Ecore_Job can be added, how it can be deleted, and that they always execute in the added order.

First, 2 callback functions are declared, one that prints strings passed to it in the data pointer, and another one that quits the main loop. In the main function, 3 jobs are added using the first callback, and another one is added using the second one.

Then the second added job is deleted just to demonstrate the usage of ecore_job_del(), and the main loop is finally started. Run this example to see that job1, job3 and job_quit are ran, in this order.

// gcc -o ecore_job_example ecore_job_example.c `pkg-config --libs --cflags ecore`

   job2 = ecore_job_add(_job_print_cb, str2);
