Hi Chaozejun!
Those files are the ones needed to perform a TCP/IP connection. They
were inherited from the BSD implementation, so the API is quite
portable. To perform such operations under Win2k you should include the
<winsock2.h> file instead. It is of course not identical to the BSD
implementation, so that you should initialize the DLL using the
following sample function:
WORD wVersionRequested;
WSADATA wsaData;
int err;
wVersionRequested = MAKEWORD( 2, 2 );
err = WSAStartup( wVersionRequested, &wsaData );
if ( err != 0 ) {
/* Tell the user that we could not find a usable */
/* WinSock DLL. */
throw runtime_error("Couldn't find winsock.");
}
/* Confirm that the WinSock DLL supports 2.2.*/
/* Note that if the DLL supports versions greater */
/* than 2.2 in addition to 2.2, it will still return */
/* 2.2 in wVersion since that is the version we */
/* requested. */
if ( LOBYTE( wsaData.wVersion ) != 2 ||
HIBYTE( wsaData.wVersion ) != 2 ) {
/* Tell the user that we could not find a usable */
/* WinSock DLL. */
WSACleanup( );
throw runtime_error("Incompatible winsock version found");
}
(you can leave out the exceptions if you are using c)
after that you can perform the connection using a BIO, i.e. platform
independently:
BIO *connector = IO_new_connect("server.name:port");
errCode = BIO_do_connect(connector);
errCode will be -1 in case of error, so check it after the function
call! Do not forget to cleanup the BIO using BIO_free() after use, since
it could lead to memory leaks...
I hope that helps!
