By Mark Weaver. * * Revision 1.4  2001/01/22 16:43:39  tng * Loads winsock dynamically.  Fixed by Curt Arnold. * Winsock2 is not initialized unless an http URL is used.    If an http * URL is used and the Winsock 2 DLL is not installed, then an NetAccessor * initialization exception is thrown. * * Revision 1.3  2000/07/21 03:22:45  andyh * Improved (but still weak) http access by the parser. * Windows only.  UNIX will follow, probably tomorrow. * * Revision 1.2  2000/03/22 00:21:10  rahulj * Now we throw exceptions when errors occur. * Simplified the code, based on the assumption that * the calling function will make sure that the buffer into * which the data has to be read is large enough. * * Revision 1.1  2000/03/17 02:37:54  rahulj * First cut at adding HTTP capability via native sockets. * Still need to add: *   error handling capability, ports other than 80, *   escaped URL's * Will add options in project file only when I am done with these * above changes. * */#if !defined(BINHTTPURLINPUTSTREAM_HPP)#define BINHTTPURLINPUTSTREAM_HPP#include <xercesc/util/XMLURL.hpp>#include <xercesc/util/XMLExceptMsgs.hpp>#include <xercesc/util/BinInputStream.hpp>#include <xercesc/util/Mutexes.hpp>#include <xercesc/util/XMLNetAccessor.hpp>//// This class implements the BinInputStream interface specified by the XML// parser.//struct hostent;struct sockaddr;XERCES_CPP_NAMESPACE_BEGINclass XMLUTIL_EXPORT BinHTTPURLInputStream : public BinInputStream{public :    BinHTTPURLInputStream(const XMLURL&  urlSource, const XMLNetHTTPInfo* httpInfo=0);    ~BinHTTPURLInputStream();    unsigned int curPos() const;    unsigned int readBytes    (                XMLByte* const  toFill        , const unsigned int    maxToRead    );	static void Cleanup();private :    // -----------------------------------------------------------------------    //  Unimplemented constructors and operators    // -----------------------------------------------------------------------    BinHTTPURLInputStream(const BinHTTPURLInputStream&);    BinHTTPURLInputStream& operator=(const BinHTTPURLInputStream&);     // -----------------------------------------------------------------------    //  Private data members    //    //  fSocketHandle    //      The socket representing the connection to the remote file.    //      We deliberately did not define the type to be SOCKET, so as to    //      avoid bringing in any Windows header into this file.    //  fBytesProcessed    //      Its a rolling count of the number of bytes processed off this    //      input stream.    //  fBuffer    //      Holds the http header, plus the first part of the actual    //      data.
