Compiler Warning (level 3) C4390

Error Message

';' : empty controlled statement found; is this the intent?

A semicolon was found after a control statement that contains no instructions.

If you get C4390 because of a macro, you should use the warning pragma to disable C4390 in the module containing the macro.

The following sample generates C4390:

// C4390.cpp
// compile with: /W3
int main() {
   int i = 0;
   if (i);   // C4390
