函数原型：

DWORD WINAPI GetCurrentDirectory(
  __in   DWORD nBufferLength,

VOID ReportError (LPCTSTR userMessage, DWORD exitCode, BOOL printErrorMessage)
{
    DWORD eMsglen;
    DWORD errNum = GetLastError();

    LPTSTR lpvSysMsg;

    _ftprintf(stderr, _T("%s\n"), userMessage);

    if (printErrorMessage) {
        eMsglen = FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, NULL, errNum, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR)&lpvSysMsg, 0, NULL);

        if (eMsglen > 0) {
            _ftprintf(stderr, _T("%s\n"), lpvSysMsg);
        }else {
            _ftprintf (stderr, _T("Last Error Number: %d.\n"), errNum);
        }
        if (lpvSysMsg != NULL) 
            LocalFree(lpvSysMsg);
    }
        if (exitCode > 0)
            ExitProcess(exitCode);

        return;
}

#define DIRNAME_LEN 1000

int _tmain(int argc, _TCHAR* argv[])
{
    TCHAR pwdBuffer[DIRNAME_LEN];
    DWORD CurDirLen;

    CurDirLen = GetCurrentDirectory(DIRNAME_LEN, pwdBuffer);

    if (CurDirLen == 0)
        ReportError(_T("Failure getting pathname."), 1, TRUE);

    if (CurDirLen > DIRNAME_LEN)
        ReportError(_T("Pathname is too long."), 2, FALSE);

    _ftprintf (stdout, _T("%s"), pwdBuffer); 

    return 0;
}
