Direct Buffer Access Interface

Overview

Functions to provide a direct buffer access to the IOCR-data.

Functions
uint32_t	PN_API_IOD_enterDbai (PN_API_IOD_Handle_t *const pnHandle)
	Acquires the semaphore of the IOD thread.
uint32_t	PN_API_IOD_exitDbai (PN_API_IOD_Handle_t *const pnHandle)
	Releases the semaphore of the IOD thread.
uint32_t	PN_API_IOD_lockDbaiBuf (PN_API_IOD_Handle_t *const pnHandle, PN_API_IOD_BufferLock_t *const lock)
	Locks a data buffer for a designated output IOCR to enable direct access to IO data.
uint32_t	PN_API_IOD_unlockDbaiBuf (PN_API_IOD_Handle_t *const pnHandle, PN_API_IOD_BufferLock_t *const lock)
	Unlocks a data buffer associated with a specified output IOCR used for direct IO data access.
