vTaskStartScheduler
[Kernel Control]

task. h

void vTaskStartScheduler( void );

Starts the real time kernel tick processing. After calling the kernel has control over which tasks are executed and when.

The idle task is created automatically when vTaskStartScheduler() is called.

If vTaskStartScheduler() is successful the function will not return until an executing task calls vTaskEndScheduler(). The function might fail and return immediately if there is insufficient RAM available for the idle task to be created.

See the demo application file main. c for an example of creating tasks and starting the kernel.

Example usage:

 void vAFunction( void )
 {
     // Create at least one task before starting the kernel.
     xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, NULL );

     // Start the real time kernel with preemption.
     vTaskStartScheduler();

     // Will not get here unless a task calls vTaskEndScheduler ()
 }
