> ## Description

> cgGetParameterResource allows the application to retrieve the resource for a parameter in a Cg program. This resource is necessary for the application to be able to supply the program's inputs and use the program's outputs.

> The resource enumerant is a profile-specific hardware resource.

> ## 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

> cgGetParameterResource was introduced in Cg 1.1.
