ID3DX11Effect::GetVariableByName method
Get a variable by name.
Syntax
ID3DX11EffectVariable* GetVariableByName(
LPCSTR Name
);
Parameters
-
Name
-
Type: LPCSTR
The variable name.
Return value
Type: ID3DX11EffectVariable*
A pointer to an ID3DX11EffectVariable. Returns an invalid variable if the specified name cannot be found.
Remarks
An effect may contain one or more variables. Variables outside of a technique are considered global to all effects, those located inside of a technique are local to that technique. You can access an effect variable using its name or with an index.
The method returns a pointer to an effect-variable interface whether or not a variable is found. ID3DX11Effect::IsValid should be called to verify whether or not the name exists.
Note
The DirectX SDK does not supply any compiled binaries for effects. You must use Effects 11 source to build your effects-type application. For more information about using Effects 11 source, see Differences Between Effects 10 and Effects 11.
