Compiler Warning (level 1) C4441

Error Message

calling convention of 'cc1' ignored; 'cc2' used instead

Member functions in managed user-defined types and global function generics must use the __clrcall calling convention. The compiler used __clrcall.


The following sample generates C4441.

// C4441.cpp
// compile with: /clr /W1 /c
generic <class ItemType>
void __cdecl Test(ItemType item) {}   // C4441
// try the following line instead
// void Test(ItemType item) {}

ref struct MyStruct {
   void __cdecl Test(){}   // C4441
   void Test2(){}   // OK
