Functions
NAIBRDFUNC nai_status_t NAIAPI	naibrd_DA_GetFIFOCount (int32_t cardIndex, int32_t module, int32_t channel, uint32_t *outcount)
	Retrieves the FIFO counter registers that indicate the number of data elements in the D/A channel's FIFO buffer. Each time a read operation is made to the D/A channel's FIFO Buffer, the corresponding FIFO counter register is decremented by one. The maximum number of items that can be stored in each D/A channel's FIFO is 26,213 (0x6665) for Gen3, DA1, DA3 and 1000000 DA2.

naibrd_DA_GetFIFOCount()

NAIBRDFUNC nai_status_t NAIAPI naibrd_DA_GetFIFOCount	(	int32_t	cardIndex,
		int32_t	module,
		int32_t	channel,
		uint32_t *	outcount )

Retrieves the FIFO counter registers that indicate the number of data elements in the D/A channel's FIFO buffer. Each time a read operation is made to the D/A channel's FIFO Buffer, the corresponding FIFO counter register is decremented by one. The maximum number of items that can be stored in each D/A channel's FIFO is 26,213 (0x6665) for Gen3, DA1, DA3 and 1000000 DA2.

Parameters

cardIndex	: (Input) Logical Card Index assigned to connection with the NAI_BOARD (0 - NAI_MAX_CARDS-1).
module	: (Input) Module Number of the module to access (1 - [max modules for board]).
channel	: (Input) Channel Number of the channel to access (1 - [max channels for module]).
outcount	: (Output) Number of data elements in FIFO Buffer.

Returns

• NAI_SUCCESS
• NAI_ERROR_INVALID_CARD when invalid card parameter is specified.
• NAI_ERROR_INVALID_MODULE when invalid module parameter is specified.
• NAI_ERROR_NOT_OPEN when handle to board is invalid.
• NAI_ERROR_INVALID_CHANNEL when invalid channel parameter is specified.
