NAME
    cgGLGetParameter - sets the value of scalar and vector parameters

SYNOPSIS
      #include <Cg/cgGL.h>

      /* type is either float or double */

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

PARAMETERS
    param   Specifies the parameter.

    v       A pointer to the buffer to return the values in.

DESCRIPTION
    The cgGLGetParameter functions extract the values set by
    cgGLSetParameter functions. The functions are available in various
    combinations.

    Each function may return either 1, 2, 3, or 4 values.

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

    The cgGLGetParameter functions may only be called with uniform
    parameters numeric parameters.

RETURN VALUES
    The cgGLGetParameter functions do not return any values.

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 handle.

    CG_INVALID_PARAMETER_ERROR is generated if the parameter fails to get
    for any other reason.
