Sending to a message buffer AND notifying a task

Hi, I am developing a software on a Cortex-M0. Each task of the system usualy wait on their notification value. When a hardware interrupt occures, I send a message to a message buffer through xMessageBufferSendFromISR and then wake the task using xTaskNotifyFromISR. As I am calling two FromISR functions I am not really sure how to handle their pxHigherPriorityTaskWoken parameters. Should I initialize it to pdFALSE, call xMessageBufferSendFromISR, portYIELD and then initialize it again, call xTaskNotifyFromISR and portYIELD ? or just initialize it once and call portYIELD each time ? or event call portYIELD only at the end ? Regards, Nathan O.

Sending to a message buffer AND notifying a task

As I am calling two FromISR functions I am not really sure how to handle their pxHigherPriorityTaskWoken parameters.
As simple as this: ~~~ void myISR() { BaseType_t xHigherPriorityTaskWoken = pdFALSE;
    xMessageBufferSendFromISR( xMessageBuffer, pvTxData, xDataLengthBytes, &xHigherPriorityTaskWoken );
    xTaskNotifyFromISR( xTask, ulValue, eSetBits, &xHigherPriorityTaskWoken );
    portYIELD_FROM_ISR( xHigherPriorityTaskWoken );
}
~~~ The two fromISR functions may set the variable xHigherPriorityTaskWoken. Once set, it won’t be cleared by a next function.

Thank you very much for your answer. I will update my code accordingly.
