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.

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