Attempt to remove the element from the front of this queue without blocking, and, if successful, load the specified `value` with the removed element. Return 0 on success, and a non‐zero value otherwise. Specifically, return `e_DISABLED` if `isPopFrontDisabled()`, and `e_EMPTY` if `!isPopFrontDisabled()` and the queue was empty. On failure, `value` is not changed.
