NAME
    cgGLGetMatrixParameter - retrieves the value of matrix parameters

SYNOPSIS
      #include <Cg/cgGL.h>

      /* type is either float or double */
      void cgGLGetMatrixParameter{fd}{rc}(CGparameter param, const type *matrix);

PARAMETERS
    param   Specifies the parameter that will be retrieved.

    matrix  An array to retrieve the matrix parameter to. The array must be
            the number of rows times the number of columns in size.

DESCRIPTION
    The cgGLGetMatrixParameter functions retrieve the value of a given
    matrix parameter. The functions are available in various combinations.

    There are versions of each function that take either float or double
    values signified by the f or d in the function name.

    There are versions of each function that assume the array of values are
    layed out in either row or column order signified by the r or c in the
    function name respectively.

    The cgGLGetMatrixParameter functions may only be called with uniform
    parameters.

RETURN VALUES
    The cgGLGetMatrixParameter functions do not return any values.

ERRORS
    CG_INVALID_PROFILE_ERROR is generated if param's profile is not a
    supported OpenGL profile.

    CG_NOT_MATRIX_PARAM_ERROR is generated if param is not a matrix
    parameter.

    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.
