hello all, i am a new user of free Rtos i am using vSemaphoreCreateBinary macro in order to create binary semaphore , as i understand, the semaphore is being created by using the heap. my question is : how can i delete this handler when i stop using it. i didnt found any macro or function that frees this allocation. so what can I do, I have memory leak problem. avi

You can actually use the vQueueDelete() function to delete semaphores too as underneath they are the same structures.
