FindNamedConstantDefinition() public méthode

Find a constant definition for a named parameter. This method returns null if the named parameter did not exist, unlike GetConstantDefinition which is more strict; unless you set the last parameter to true.
public FindNamedConstantDefinition ( string name, bool throwExceptionIfNotFound ) : GpuConstantDefinition
name string The name to look up
