Adding Multitasking Capability to Applications Using Multiprocessing Services

MPCurrentTaskID

Obtains the task ID of the currently-executing preemptive task



 
MPTaskID MPCurrentTaskID (void);

function result: A value of type MPTaskID that specifies the task ID of the current preemptive task.

DISCUSSION

Returns the ID of the current preemptive task. If called from a cooperative task, this function returns an ID which is different than the ID of any preemptive task. Nonpreemptive processes may or may not have different task IDs for each application; future implementations of this API may behave differently in this regard.

Note that you can call this function from an interrupt handler.

VERSION NOTES

Introduced with Multiprocessing Services 1.0.
