ecore_job - Queuing tasks
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.
//Compile with: // gcc -o ecore_job_example ecore_job_example.c `pkg-config --libs --cflags ecore` #include <Ecore.h> #include <unistd.h> static void _job_print_cb(void *data) { char *str = data; printf("%s\n", str); } static void _job_quit_cb(void *data EINA_UNUSED) { ecore_main_loop_quit(); } int main(void) { Ecore_Job *job1, *job2, *job3, *job_quit; char *str1 = "Job 1 started."; char *str2 = "Job 2 started."; char *str3 = "Job 3 started."; if (!ecore_init()) { printf("ERROR: Cannot init Ecore!\n"); return -1; } job1 = ecore_job_add(_job_print_cb, str1); job2 = ecore_job_add(_job_print_cb, str2); job3 = ecore_job_add(_job_print_cb, str3); job_quit = ecore_job_add(_job_quit_cb, NULL); (void)job1; (void)job3; (void)job_quit; printf("Created jobs 1, 2, 3 and quit.\n"); if (job2) { char *str; str = ecore_job_del(job2); job2 = NULL; printf("Deleted job 2. Its data was: \"%s\"\n", str); } ecore_main_loop_begin(); ecore_shutdown(); return 0; }
