DEV-C++中的编译器错误

Question

我编译了下面的代码，它是在我的C代码中用#include <strsafe.h>声明的，在DEV-C++中我得到了以下编译器错误。我想在编译器中应该有一些选项来解决这个问题。有人能帮我解决这个问题吗。

下面是我的示例代码，取自MSDN站点：

#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"));
}

我从中得到上述错误的strsafe.h文件的一部分：

// be null terminated.

Answer 1

__nullterminated，__out_opt，__in，__in_opt和其他类似的词都是微软特有的关键词。使用gcc时，您可以将它们定义为空宏，如下所示

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

在includes之前插入这些定义。

或者正如评论所建议的那样，避免使用<strsafe.h>

编辑：

MinGW (来自http://equation.com的x64构建)只需一条简单的命令就可以安静地编译上面的代码(即使使用strsafe.h)：

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