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[in]	inSynchronous	This parameter is obsolete, and ignored.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]	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]	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.

virtual

Reads all or part of the 32-bit contents of a specific register (real or virtual) on the AJA device. Using the optional mask and shift parameters, it's possible to read any number of specific bits in a register while ignoring the register's other bits.

Returns: True if successful; otherwise false.

Parameters

[in]	inRegNum	Specifies the register number of interest.
[out]	outValue	Receives the register value obtained from the device.
[in]	inMask	Optionally specifies a bit mask to be applied after reading the device register. Zero and 0xFFFFFFFF masks are ignored. Defaults to 0xFFFFFFFF (no masking).
[in]	inShift	Optionally specifies the number of bits to right-shift the value obtained from the device register after the mask has been applied. Defaults to zero (no shift).

Note: This function should be used only when there is no higher-level function available to accomplish the desired task.; The mask and shift parameters are ignored when reading a virtual register.

virtual

Updates or replaces all or part of the 32-bit contents of a specific register (real or virtual) on the AJA device. Using the optional mask and shift parameters, it's possible to set or clear any number of specific bits in a real register without altering any of the register's other bits.

Returns: True if successful; otherwise false.

Parameters

[in]	inRegNum	Specifies the register number of interest.
[in]	inValue	Specifies the desired new register value. If the "inShift" parameter is non-zero, this value is shifted left by the designated number of bit positions before being masked and applied to the real register contents.
[in]	inMask	Optionally specifies a bit mask to be applied to the new (shifted) value before updating the register. Defaults to 0xFFFFFFFF, which does not perform any masking. On Windows and MacOS, a zero mask is treated the same as 0xFFFFFFFF.
[in]	inShift	Optionally specifies the number of bits to left-shift the specified value before applying it to the register. Defaults to zero, which does not perform any shifting. On MacOS, this parameter is ignored. On Windows, a shift value of 0xFFFFFFFF is treated the same as a zero shift value.

Note: This function should be used only when there is no higher-level function available to accomplish the desired task.; The mask and shift parameters are ignored when setting a virtual register.

Bug:: On MacOS, "holes" in the mask (i.e., one or more runs of 0-bits lying between more-significant and less-significant 1-bits) were not handled correctly.
