写二进制文件

BYTE  p[4] = {11,12,13,14};
std::string datFilename = "111111.dat";
std::ofstream dataStream(
	datFilename.c_str(), std::ios::binary | std::ios::trunc | std::ios::out);
dataStream.exceptions(std::ios::failbit | std::ios::badbit);
//dataStream.write(reinterpret_cast<const char*>(buffer16), bufferWidth * bufferHeight * 2);
dataStream.write(reinterpret_cast<const char*>(p), 4);
//dataStream.write((const char*)p, 4);
dataStream.close();
