NAME
cgGLGetMatrixParameterArraydc - get the values from a matrix array parameter
SYNOPSIS
#include <Cg/cgGL.h> void cgGLGetMatrixParameterArraydc( CGparameter param, long offset, long nelements, double * v );PARAMETERS
- param
The array parameter.
- offset
An offset into the array parameter from which to start getting. A value of 0 will start getting from the first element of the array.
- nelements
The number of elements to get. A value of 0 will default to the number of elements in the array minus the offset value.
- v
The array into which to retrieve the values. The size of v must be nelements times the number of elements in the matrix.
RETURN VALUES
None.
DESCRIPTION
cgGLGetMatrixParameterArraydc retrieves an array of values in column-major order from a given matrix array parameter.

ERRORS
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_NOT_MATRIX_PARAM_ERROR is generated if the elements of the array indicated by param are not matrix parameters.
CG_OUT_OF_ARRAY_BOUNDS_ERROR is generated if the offset and/or the nelements parameter are out of the array bounds.
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter handle.
CG_INVALID_PARAMETER_ERROR is generated if the parameter fails to retrieve for any other reason.
HISTORY
cgGLGetMatrixParameterArraydc was introduced in Cg 1.1.
