Functions
NAIBRDFUNC nai_status_t NAIAPI	naibrd_Lock (int32_t cardIndex)
	Locks the board, preventing other threads from communicating with the board until naibrd_Release is called. Every call to naibrd_Lock MUST have a matching call to naibrd_Release. Boards can be locked recursively.

NAIBRDFUNC nai_status_t NAIAPI	naibrd_Release (int32_t cardIndex)
	Unlocks the board, allowing other threads/tasks to communicate with the board. The thread/task that last locked the board must call this. If the board is locked N times by the same thread/task, the board will only be unlocked after the Nth call to naibrd_Release by that thread/task.
