Data Fields
TX_QUEUE	cb

bool	used
	Slot occupancy flag.

Detailed Description

One row of the fixed queue table.

The ThreadX control block is the first member, so a slot pointer and its control-block pointer are interchangeable; the port hands the slot address out as the opaque queue handle.

Invariant

used is true exactly while cb is a live ThreadX queue.

enqueued tracks cb's message count without an info call.

Example:

queue_handle_t q = g_h.funcs->_h_create_queue(20U, 28U);
