vTaskPrioritySet

h

void vTaskPrioritySet( xTaskHandle pxTask, unsigned portBASE_TYPE uxNewPriority );

INCLUDE_vTaskPrioritySet must be defined as 1 for this function to be available. See the configuration section for more information.

Set the priority of any task.

A context switch will occur before the function returns if the priority being set is higher than the currently executing task.

Parameters:

	pxTask	Handle to the task for which the priority is being set. Passing a NULL handle results in the priority of the calling task being set.
	uxNewPriority	The priority to which the task will be set.

Example usage:

 void vAFunction( void )
 {
 xTaskHandle xHandle;

Create a task, storing the handle.
	 xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &xHandle );

...

Use the handle to raise the priority of the created task.
	 vTaskPrioritySet( xHandle, tskIDLE_PRIORITY + 1 );

...

Use a NULL handle to raise our priority to the same value.
	 vTaskPrioritySet( NULL, tskIDLE_PRIORITY + 1 );
 }
