int RTX_Task_Priority ( RTX_ID  taskId,
int  priority 

This API changes and/or reads out a task's priority.

To make a read-only call with no priority change, set the priority argument to PRIORITY_READ_ONLY.

The existing task priority reported in the return value does not reflect any momentary priority boost which this task may be receiving due a priority inheritance semaphore or file system semaphore. The task's native priority is reported.

taskId Task handle specifying task whose priority is to be changed. This parameter may be set to zero to indicate the current task.
priority Task priority, ranging from 2 (highest) up to 127 (lowest). Or set to PRIORITY_READ_ONLY if no change is desired.
Positive value: Existing task priority before change
Negative value: An RTX error code.
