Is there a call which return space available of a queue set.
Calling uxQueueSpaceAvailable() on the queue set itself will return the space within the queue set (which is itself implemented using a queue - hence the queue functions work on the sets too).
1,surprised for the function was implemented by FreeRTOS already. 2:surprised for the function hide there if no one mention it.
Please add mark to any function can/can’t use in ISR on https://www.freertos.org/a00018.html#uxQueueSpacesAvailable
For example I didn’t know can I use uxQueueSpaceAvailable() in ISR or not.
FreeRTOS functions not ending in
FromISR cannot be called from ISR.
