> cgGetParameterResourceName allows the application to retrieve the resource name for a parameter in a Cg program. For translated profiles this name will most likely be different from the string returned by cgGetResourceString.

> ## Examples

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

>     printf("Resource: %s:%d (base %s) [name:%s]\n",
>       cgGetResourceString(cgGetParameterResource(param)),
>       cgGetParameterResourceIndex(param),
>       cgGetResourceString(cgGetParameterBaseResource(param)),
>       cgGetParameterResourceName(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

> cgGetParameterResourceName was introduced in Cg 2.1.
