如何判斷我正在運行的Microsoft C++代碼是使用/ EHa開關編譯的？

Question

我需要確保我正在使用的頭與/ EHa編譯器開關編譯？

我該怎麼做？

Answer 1

inline bool CodeHasEHaSwitch() 
{ 
    bool dtorCalled = false; 

    struct CCheckEHaSwitch 
    { 
     CCheckEHaSwitch(bool& dtorCalled) : dtorCalled(dtorCalled) {} 
     ~CCheckEHaSwitch() { dtorCalled = true; } 
     bool& dtorCalled; 

     static void Win32ExceptionTranslator(unsigned int nExceptionCode, 
     EXCEPTION_POINTERS *pExceptionInfo) 
     { throw nExceptionCode; } 
    }; 

    _se_translator_function pfnPrevSeTranslator = 
     _set_se_translator(CCheckEHaSwitch::Win32ExceptionTranslator); 
    try 
    { 
     CCheckEHaSwitch test(dtorCalled); 

     *((int*)0) = 0; // generate access violation 
    } 
    catch (unsigned int) 
    { 
    } 

    _set_se_translator(pfnPrevSeTranslator); 

    return dtorCalled; 
}
