	)

virtual

Transfers data between the AJA device and the host. This function will block and not return to the caller until the transfer has finished or failed.

Parameters

[in]	inDMAEngine	Specifies the device DMA engine to use. Use NTV2_DMA_FIRST_AVAILABLE for most applications. (Use the NTV2DeviceGetNumDMAEngines function to determine how many are available.)
[in]	inIsRead	Specifies the transfer direction. Use 'true' for reading (device-to-host). Use 'false' for writing (host-to-device).
[in]	inFrameNumber	Specifies the zero-based frame number of the starting frame to be transferred to/from the device.
	pFrameBuffer	Specifies a valid, non-NULL address of the host buffer. If reading (device-to-host), this memory will be written into. If writing (host-to-device), this memory will be read from.
[in]	inCardOffsetBytes	Specifies the byte offset into the device frame buffer where the data transfer will start.
[in]	inTotalByteCount	Specifies the total number of bytes to be transferred.
[in]	inSynchronous	This parameter is obsolete, and ignored.

Returns: True if successful; otherwise false.

Note: The host buffer must be at least inByteCount + inOffsetBytes in size; otherwise, host memory will be corrupted, or a bus error or other runtime exception may occur.

	)

virtual

Transfers data in segments between the AJA device and the host. This function will block and not return to the caller until the transfer has finished or failed.

Parameters

[in]	inDMAEngine	Specifies the device DMA engine to use. Use NTV2_DMA_FIRST_AVAILABLE for most applications. (Use the NTV2DeviceGetNumDMAEngines function to determine how many are available.)

[in]	inFrameNumber	Specifies the zero-based frame number of the starting frame to be transferred to/from the device.
	pFrameBuffer	Specifies a valid, non-NULL address of the host buffer. If reading (device-to-host), this memory will be written into. If writing (host-to-device), this memory will be read from.
[in]	inCardOffsetBytes	Specifies the byte offset into the device frame buffer where the data transfer will start.
[in]	inTotalByteCount	Specifies the total number of bytes to be transferred.
[in]	inNumSegments	Specifies the number of segments to transfer. Note that this determines the number of bytes per segment (by dividing into inTotalByteCount).
[in]	inHostPitchPerSeg	Specifies the number of bytes to increment the host memory pointer after each segment is transferred.
[in]	inCardPitchPerSeg	Specifies the number of bytes to increment the on-device memory pointer after each segment is transferred.
[in]	inSynchronous	This parameter is obsolete, and ignored.

Returns: True if successful; otherwise false.

Note: The host buffer must be at least inByteCount + inOffsetBytes in size; otherwise, host memory will be corrupted, or a bus error or other runtime exception may occur.
