IMAQdxReadRegister

Format

rval = IMAQdxReadRegister (IMAQdxSession id, unsigned int offset, unsigned int *value);

Purpose

Accesses registers on the camera and reads a 32-bit value from the camera. Data is byte-swapped for little endian alignment after transfer.

Parameters

Parameter	Type	Description
id	IMAQdxSession	A valid Session ID, which you can obtain using IMAQdxOpenCamera.
offset	unsigned int	The register location to access. Refer to the camera documentation for more information about camera-specific register ranges. Use attribute IMAQdxAttributeBaseAddress to obtain the base address for the camera.
value	unsigned int (passed by reference)	Specifies the value to read from the memory offset.

Return Value

On success, this function returns IMAQdxErrorSuccess. On failure, this function returns an error code. You can obtain a more detailed error message with IMAQdxGetErrorString.
