Question

我编译了以下代码，该代码在我的C代码中用#include <strsafe.h>声明，我在DEV-C ++中遇到以下编译器错误。我想编译器中应该有一些选项来解决这个问题。有人可以帮忙解决这个问题。

以下是我的示例代码，该代码取自MSDN网站：

#include <windows.h>
#include <strsafe.h>

void ErrorExit(LPTSTR lpszFunction) 
{ 
    // Retrieve the system error message for the last-error code

    LPVOID lpMsgBuf;
    LPVOID lpDisplayBuf;
    DWORD dw = GetLastError(); 

    FormatMessage(
        FORMAT_MESSAGE_ALLOCATE_BUFFER | 
        FORMAT_MESSAGE_FROM_SYSTEM |
        FORMAT_MESSAGE_IGNORE_INSERTS,
        NULL,
        dw,
        MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
        (LPTSTR) &lpMsgBuf,
        0, NULL );

    // Display the error message and exit the process

    lpDisplayBuf = (LPVOID)LocalAlloc(LMEM_ZEROINIT, 
        (lstrlen((LPCTSTR)lpMsgBuf) + lstrlen((LPCTSTR)lpszFunction) + 40) * sizeof(TCHAR)); 
    StringCchPrintf((LPTSTR)lpDisplayBuf, 
        LocalSize(lpDisplayBuf) / sizeof(TCHAR),
        TEXT("%s failed with error %d: %s"), 
        lpszFunction, dw, lpMsgBuf); 
    MessageBox(NULL, (LPCTSTR)lpDisplayBuf, TEXT("Error"), MB_OK); 

    LocalFree(lpMsgBuf);
    LocalFree(lpDisplayBuf);
    ExitProcess(dw); 
}

void main()
{
    // Generate an error

    if(!GetProcessId(NULL))
        ErrorExit(TEXT("GetProcessId"));
}

大量错误中的错误示例。

我收到上述错误的strsafe.h文件的一部分：

Answer 1

__ nullterminated，__ out_opt，__ in，__ in_opt和其他此类单词是Microsoft特定的关键字。当你使用gcc时，你可以将它们定义为空的宏，如

#define __in
#define __deref_out_range(A,B)
... and so on

在包含之前插入这些定义。

或者评论建议避免使用<strsafe.h>

编辑：

MinGW（来自http://equation.com的x64版本）只需一个简单的命令就可以安静地编译上面的代码（即使只有strsafe.h）：

gcc -c Test.cpp -o Test.exe -lstdc++
