expected formal parameter list, not a type list

A function definition contains a parameter type list instead of a formal parameter list. ANSI C requires formal parameters to be named unless they are void or an ellipsis (...).

The following sample generates C2055:

// C2055.c  
// compile with: /c  
void func(int, char) {}  // C2055  
void func (int i, char c) {}   // OK
