> ## Description

> The parameters of a effect can be retrieved directly by name using cgGetNamedEffectParameter. The names of the parameters in a effect can be discovered by iterating through the effect's parameters (see cgGetFirstEffectParameter and cgGetNextParameter), calling cgGetParameterName for each one in turn.

> The given name may be of the form "foo.bar[2]", which retrieves the second element of the array "bar" in a structure named "foo".

> ## Examples

> to-be-written

> ## Errors

> CG_INVALID_EFFECT_HANDLE_ERROR is generated if effect is not a valid effect.

> ## History

> cgGetNamedEffectParameter was introduced in Cg 1.4.
