Compiler Warning (level 1) C4033 (original) (raw)

'function' must return a value

Remarks

The function does not return a value. An undefined value is returned.

Functions that use return without a return value must be declared as type void.

This error is for C language code.

Example

The following example generates C4033:

// C4033.c
// compile with: /W1 /LD
int test_1(int x)   // C4033 expected
{
   if (x)
   {
      return;   // C4033
   }
}
