Now, let's suppose that ::string 41 // is different that std::string and you'd like to have the option to easily 42 // choose between the two string types. Ideally you'd like to control which 43 // string type is chosen by simply #defining an identifier. 44 // 45 // The solution: 46 // ------------- 47 // #define HAS_GLOBAL_STRING somewhere in a global header file and then 48 // globally replace std::string with string. Then include this header 49 // file everywhere where string is used. If you want to revert back to 50 // using std::string, simply remove the #define (HAS_GLOBAL_STRING). 51 52 #ifndef THIRD_PARTY_BREAKPAD_SRC_COMMON_USING_STD_STRING_H_ 53 #define THIRD_PARTY_BREAKPAD_SRC_COMMON_USING_STD_STRING_H_ 54 55 #ifdef HAS_GLOBAL_STRING 56 typedef ::string google_breakpad_string; 57 #else 58 using std::string; 59 typedef std::string google_breakpad_string; 60 #endif 61 62 // Inicates that type google_breakpad_string is defined 63 #define HAS_GOOGLE_BREAKPAD_STRING 64 65 #endif // THIRD_PARTY_BREAKPAD_SRC_COMMON_USING_STD_STRING_H_ 66
