HP–Socket 是一套通用的高性能 TCP/UDP/HTTP 通信框架，这里记录的是通过 HP–Socket 发送小文件的功能，代码如下：

p-> GetCurrentImage();

CFile file (_T("$shs.jpg"), CFile::modeRead );
auto uLen = file. GetLength();
file. Close();

TPkgHeader * header = new TPkgHeader ();
header-> seq = NET_SSH_SCREEN;
header-> body_len = uLen;

WSABUF buf ;
buf. len = sizeof (TPkgHeader );
buf. buf = (CHAR *)header ;

p-> m_pSocket-> GetTcpPullClientPtr()->SendSmallFile (_T("$shs.jpg"), &buf, NULL );
