- offset
- An offset into the array parameter at which to start getting elements. A value of 0 will begin at the first element of the array.
- nelements
- The number of elements to get. A value of 0 will default to the total number of elements in the array minus the value of offset.
- v
- Destination buffer into which the values will be written. The size of v must be 4 * nelements.

CG_INVALID_PROFILE_ERROR is generated if param's profile is not a supported OpenGL profile.CG_ARRAY_PARAM_ERROR is generated if param is not an array parameter.
CG_OUT_OF_ARRAY_BOUNDS_ERROR is generated if offset or nelements is outside the bounds of param.
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
