std::ofstream由二进制流写文件的问题

从MPQ包中读取二进制流出来然后文件写到硬盘。

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，等文本都是对的，唯独.jpg这些图片些不对！

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

就对了！

原因应该是ofstream打开文件时默认是文本格式吧。。。

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
);
