Pragmas for Diagnostic Messages

31.1 extended_errorcheck

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

Syntax

#pragma extended_errorcheck on | off | reset

Remarks

If you enable this pragma, the compiler generates a warning message (not an error) if it encounters some common programming 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 listing below shows an example.

Listing 31-1. Attempting to delete an undefined structure

#pragma extended_errorcheck on struct X; int func(X *xp)

{

delete xp; // Warning: deleting incomplete type X

}

• An integer or floating-point value assigned to an enum

type. The listing below shows an example.

Listing 31-2. Assigning to an Enumerated Type

enum Day { Sunday, Monday, Tuesday, Wednesday,

Thursday, Friday, Saturday } d; d = 5; /* WARNING */ d = Monday; /* OK */ d = (Day)3; /* OK */
