MPU_vTaskPrioritySet() - syntax, references, call tree, description

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. Example usage:

 void vAFunction( void )
 {
 TaskHandle_t 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 );
 }
   

Arguments

xTask

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.
