std::ofstream由二進位制流寫檔案的問題

從MPQ包中讀取二進位制流出來然後檔案寫到硬碟。

DWORD size = SFileGetSize(hFile);

char* buffer = new char[size];

std::ofstream ofs;

ofs.open(name);

ASSERT(ofs.good());

ofs.write(buffer, size);

ASSERT(ofs.good());

ofs.close();

.xml，.lua，等文字都是對的，唯獨.jpg這些圖片些不對！

open改為ofs.open(name, std::ios::out | std::ios::binary);

就對了！

原因應該是ofstream開啟檔案時預設是文字格式吧。。。

void open(
    const char *_Filename,
    ios_base::openmode _Mode = ios_base::out,
    int _Prot = (int)ios_base::_Openprot
);
void open(
    const char *_Filename,
    ios_base::openmode _Mode
);
void open(
    const wchar_t *_Filename,
    ios_base::openmode _Mode = ios_base::out,
    int _Prot = (int)ios_base::_Openprot
);
void open(
    const wchar_t *_Filename,
    ios_base::openmode _Mode
);
