Compiler Error C2860

  • Article

'void' cannot be used as a function parameter except for '(void)'

A function parameter cannot be of type void.

The following sample generates C2860:

// C2860.cpp
// compile with: /c
void func1(void x);   // C2860
void func2(void, int y);   // C2860
void func3(void);   // OK
