extended_errorcheck

Controls the issuing of warning messages for possible unintended logical errors.

  #pragma extended_errorcheck on | off | reset
  
  

If you enable this pragma, the C++ compiler generates a warning message for the possible unintended logical errors.

It also issues a warning message when it encounters a delete operator for a class or structure that has not been defined yet. The following listing shows an example.

#pragma extended_errorcheck on

struct X;

int func(X *xp)

{

     delete xp;    // Warning: deleting incomplete type X

}

• An empty return statement in a function that is not declared void. For example, The following listing results in a warning message.
  Listing: A non-void function with an empty return statement

  
  int MyInit(void)
  
  {
  
    int err = GetMyResources();
  
    if (err != -1)
  
    {
  
      err = GetMoreResources();
  
    }
  
    return; /* WARNING: empty return statement */
  
  }
  

  The following listing shows how to prevent this warning message.

  Listing: A non-void function with a proper return statement

  
  int MyInit(void)
  
  {
  
    int err = GetMyResources();
  
    if (err != -1)
  
    {
  
      err = GetMoreResources();
  
    }
  
    return err; /* OK */
  
  }
