    cgGLGetParameter - get the values from a scalar or vector parameter

SYNOPSIS
      #include <Cg/cgGL.h>

      /* TYPE is float or double */

      void cgGLGetParameter{1234}{fd}( CGparameter param,
                                       TYPE * v );

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

    v       Destination buffer into which the values will be written.

RETURN VALUES

DESCRIPTION
    The cgGLGetParameter functions extract the values set by
    cgGLSetParameter functions.

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

    Each function returns either 1, 2, 3, or 4 values.

    These functions may only be called with uniform numeric parameters.

EXAMPLES
    *to-be-written*

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

    CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid
    parameter.

HISTORY
    The cgGLGetParameter functions were introduced in Cg 1.1.
