NAME
    cgGLGetMatrixParameter - get the values from a matrix parameter

SYNOPSIS
      #include <Cg/cgGL.h>

      /* TYPE is float or double */

      void cgGLGetMatrixParameter{fd}{rc}( CGparameter param,
                                           TYPE * matrix );

PARAMETERS
    param   The matrix parameter from which the values will be retrieved.

    matrix  An array into which the values will be retrieved. The size must
            be the number of rows times the number of columns of param.

RETURN VALUES
    None.

DESCRIPTION
    The cgGLGetMatrixParameter functions retrieve the values from a matrix
    parameter.

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

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

    The cgGLGetMatrixParameter functions may only be called with uniform
    parameters.

EXAMPLES
    *to-be-written*

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.

HISTORY
    The cgGLGetMatrixParameter functions were introduced in Cg 1.1.
