xTimerStopFromISR macro

BaseType_t xTimerStopFromISR( TimerHandle_t xTimer, BaseType_t *pxHigherPriorityTaskWoken ); A version of xTimerStop() that can be called from an interrupt service routine. Example usage: @verbatim // This scenario assumes xTimer has already been created and started. When // an interrupt occurs, the timer should be simply stopped. // The interrupt service routine that stops the timer. void vAnExampleInterruptServiceRoutine( void ) { BaseType_t xHigherPriorityTaskWoken = pdFALSE; // The interrupt has occurred - simply stop the timer. // xHigherPriorityTaskWoken was set to pdFALSE where it was defined // (within this function). As this is an interrupt service routine, only // FreeRTOS API functions that end in "FromISR" can be used. if( xTimerStopFromISR( xTimer, &xHigherPriorityTaskWoken ) != pdPASS ) { // The stop command was not executed successfully. Take appropriate // action here. } // If xHigherPriorityTaskWoken equals pdTRUE, then a context switch // should be performed. The syntax required to perform a context switch // from inside an ISR varies from port to port, and from compiler to // compiler. Inspect the demos for the port you are using to find the // actual syntax required. if( xHigherPriorityTaskWoken != pdFALSE ) { // Call the interrupt safe yield function here (actual function // depends on the FreeRTOS port being used). } } @endverbatim
