675
676 Stringify macros to process raw text passed via -D options to C string constants. The double-wrapping is necessary
677 because the C preprocessor doesn't perform its normal argument expansion pre-scan with stringified macros so the
678 -D macro needs to be expanded once via the wrapper macro then stringified so the raw text is stringified. Otherwise,
679 the replacement value would be used instead of the symbolic name (only for preprocessor symbols like #defines).
680
681 For example:
682
683 #define kMyConstant 1
684
685 printf( "%s", Stringify( kMyConstant ) ); // Prints "kMyConstant"
686 printf( "%s", StringifyExpansion( kMyConstant ) ); // Prints "1"
687
688 Non-preprocessor symbols do not have this issue. For example:
689
690 enum
691 {
692 kMyConstant = 1
693 };
694
695 printf( "%s", Stringify( kMyConstant ) ); // Prints "kMyConstant"
696 printf( "%s", StringifyExpansion( kMyConstant ) ); // Prints "kMyConstant"
697
698 See <http://gcc.gnu.org/onlinedocs/cpp/Argument-Prescan.html> for more info on C preprocessor pre-scanning.
