> ## Name

> cgGetNamedStructParameter - get member of a struct parameter by name

> ## Synopsis

>     #include <Cg/cg.h>

>     CGparameter cgGetNamedStructParameter( CGparameter param,
>                                            const char * name );

> ## Parameters

> param
>   The struct parameter from which to retrieve the member parameter.
> name
>   The name of the member parameter to retrieve.

> ## Return Values

> Returns the member parameter from the given struct.

> Returns NULL if the struct has no member parameter corresponding to name.

> ## Description

> The member parameters of a struct parameter may be retrieved directly by name using cgGetNamedStructParameter.

> The names of the parameters in a struct may be discovered by iterating through the struct's member parameters (see cgGetFirstStructParameter and cgGetNextParameter), and calling cgGetParameterName for each one in turn.

> ## Examples

> to-be-written

> ## Errors

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

> CG_INVALID_PARAMETER_TYPE_ERROR is generated if param is not a struct parameter.

> ## History

> cgGetNamedStructParameter was introduced in Cg 1.2.
