Function Documentation

void op_KernelStart ( void )

Starts the kernel by launching the highest priority task ready to run. If there's been no call to op_TaskStart before entering op_KernelStart, the idle task will be made ready to run and the system will be freezed waiting for an interrupt or anything. So don't forget to create at least one task before calling op_KernelStart.
op_KernelStart never returns except if op_KernelStop is called.

void op_KernelStop ( void )

Stops all running tasks, and exits the kernel multithreading. The effect is just that op_KernelStart seemes to return, and so the code after the call to op_KernelStart will be executed.
Remember that it won't free ressources allocated by the tasks.
