            How to Open a File in Shared Mode Using Streams


       The following example shows how to use streams with files
  which must be opened in SHARED mode.  The basic idea is to create
  a stream that uses the file handle that was obtained from sopen()
  [ i.e. the handle to a shared file ].


       #include <io.h>
       #include <fcntl.h>
       #include <sys\stat.h>
       #include <process.h>
       #include <share.h>
       #include <stdio.h>
       #include <fstream.h>
       #include <iostream.h>

       const int BUFSIZE = 80;
       const char fname[15] = "c:\\delete.me";

       void main( void )
       {
            int handle;
            char buffer[BUFSIZE];

            //  First we need to open a file using sopen().
            handle = sopen( fname, O_CREAT | O_RDWR, SH_DENYNO,
                            S_IREAD | S_IWRITE );

            if ( !handle )
            {
                 printf( "sopen() failed\n" );
                 exit( 1 );
            }


            fstream cppstream( handle );       //  input and output

            cppstream.write( "This file is open for sharing\n",
                              31 );

            cppstream.seekg( 0L, ios::beg );   //  go to beginning
            cppstream.getline( buffer, BUFSIZE );//  get first line
            cout << buffer;     //  write the line to the screen

            close( handle );
