=Task Queue=
Task Queue Pointer Offset: 0x1481FFA50 (v1.07)<br>
At the start an ROOT task is created.<br>
When the ROOT task was created the Queue gets filled with NONE task's which do nothing.

=Enqueue Task=

==Enqueue task without parameter==
To enqueue an task without parameter the subroutine 0x14049D890 (v1.07) needs to be called.

==Enqueue task with parameter==
To enqueue an task with parameter the subroutine 0x14049DA10 (v1.07) needs to be called.

==Task creation==
During the enqueue process the task will be created with the given callback function.<br>
The callback function parameter, which is optional, is an pointer to an struct than can have any shape or size the callback function needs.

=Task execution=
The main loop iterates through the task queue and calls the callback function with the optional parameter.<br>
When the callback function returns the next task pointer is read from the current task and moved into the task queue address pointer.
