The function CODirFind() is often called from the application to get an object directory entry. The following example checks the existence of the mandatory object entry "[1017:00] - Heartbeat" within the object directory of the CANopen node AppNode.

    CO_OBJ *obj;
    :
    obj = CODirFind (&(AppNode.Dir), CO_DEV(0x1017, 0x00));
    if (obj == 0) {
        /* object [1017:00] is missing */
    } else {
        /* object [1017:00] is available */
    }
    :

Note: When using static object directories, the pointer to the identified object entry can be stored and reused with the object entry API functions. The object entry address will NOT change.
