NAME
    cgGetParameterBaseResource - get a parameter's base resource

SYNOPSIS
      #include <Cg/cg.h>

      CGresource cgGetParameterBaseResource( CGparameter param );

PARAMETERS
    param   The parameter.

RETURN VALUES
    Returns the base resource of param.

    Returns CG_UNDEFINED if no base resource exists for the given parameter.

DESCRIPTION
    cgGetParameterBaseResource allows the application to retrieve the base
    resource for a parameter in a Cg program. The base resource is the first
    resource in a set of sequential resources. For example, if a given
    parameter has a resource of CG_ATTR7, it's base resource would be
    CG_ATTR0. Only parameters with resources whose name ends with a number
    will have a base resource. For all other parameters the undefined
    resource CG_UNDEFINED will be returned.

    The numerical portion of the resource may be retrieved with
    cgGetParameterResourceIndex. For example, if the resource for a given
    parameter is CG_ATTR7, cgGetParameterResourceIndex will return 7.

EXAMPLES
      /* log info about parameter param for debugging */

      printf("Resource: %s:%d (base %s)\n", 
        cgGetResourceString(cgGetParameterResource(param)),
        cgGetParameterResourceIndex(param),
        cgGetResourceString(cgGetParameterBaseResource(param)));

ERRORS
    CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid
    parameter.

    CG_INVALID_PARAMETER_ERROR is generated if param is not a leaf node.

HISTORY
    cgGetParameterBaseResource was introduced in Cg 1.1.
