Chapter 31 Pragmas for Diagnostic Messages

Controls the recognition of conflicts involving case-sensitive filenames within system includes.

Syntax

#pragma warn_filenamecaps_system on | off | reset

Remarks

If you enable this pragma along with warn_filenamecaps

, the compiler issues a warning message when an

#include

directive capitalizes a filename within a system include differently from the way the filename appears on a disk. It also detects use of "8.3" DOS filenames in Windows® systems when a long filename is available. This pragma helps avoid porting problems to operating systems with case-sensitive file names.

To check the spelling of system includes such as the following:

#include <file>

Use this pragma along with the warn_filenamecaps pragma.

By default, this pragma is off.

NOTE

Some SDKs (Software Developer Kits) use "colorful" capitalization, so this pragma may issue a lot of unwanted messages.

31.16 warn_hiddenlocals

Controls the recognition of a local variable that hides another local variable.

Syntax

#pragma warn_hiddenlocals on | off | reset

Remarks

When on

, the compiler issues a warning message when it encounters a local variable that

hides another local variable. An example appears in Listing 31-11 on page 489 .

Listing 31-11. Example of hidden local variables warning
