  • Article

Attributes cannot be applied to C++ varargs

An attribute was applied incorrectly. Attributes can not be applied to an ellipsis representing variable arguments.

For more information, see User-Defined Attributes.

Example

The following sample generates C3133.

// C3133.cpp
// compile with: /clr /c
ref struct MyAttr: System::Attribute {};
void Func([MyAttr]...);   // C3133
void Func2([MyAttr] int i);   // OK
