Generally you would have a circular queue of pointers to struct on the transmission queue. You don't want to be copying data around when you don't have to and it means the transmission queue is always just a pointer that the transmission sender can check what the pointer points to. In your struct you could have for example a field which would be "size to send" and then the data. You either free the struct after sending if dynamic, or clear a flag in the struct to mark it free for reuse if using static structs.

As you are feeding two threads into one queue you will also need to put a binary semaphore on queue access.
