678
679 Stringify macros to process raw text passed via -D options to C string constants. The double-wrapping is necessary
680 because the C preprocessor doesn't perform its normal argument expansion pre-scan with stringified macros so the
681 -D macro needs to be expanded once via the wrapper macro then stringified so the raw text is stringified. Otherwise,
682 the replacement value would be used instead of the symbolic name (only for preprocessor symbols like #defines).
683
684 For example:
685
686 #define kMyConstant 1
687
688 printf( "%s", Stringify( kMyConstant ) ); // Prints "kMyConstant"
689 printf( "%s", StringifyExpansion( kMyConstant ) ); // Prints "1"
690
691 Non-preprocessor symbols do not have this issue. For example:
692
693 enum
694 {
695 kMyConstant = 1
696 };
697
698 printf( "%s", Stringify( kMyConstant ) ); // Prints "kMyConstant"
699 printf( "%s", StringifyExpansion( kMyConstant ) ); // Prints "kMyConstant"
700
701 See <http://gcc.gnu.org/onlinedocs/cpp/Argument-Prescan.html> for more info on C preprocessor pre-scanning.
