Help with http_protocol.c

[Shezaan Topiwala]

Hi,
The following snippet of code is from the http_protocol.c from 
Apache1.3. I would like to know what its equivalent would be in  
Apache2.0. Here is the code.

static int send_buffer( request_rec *r, void *buf, size_t len ){
 unsigned written;

 written = ap_bwrite( r->connection->client, buf, len );

 if (written > 0)
   ap_reset_timeout(r);
 else
   if (written < 0){
     if (!r->connection->aborted){
   ap_log_rerror( APLOG_MARK, APLOG_INFO,0,r,
              "client stopped connection before send body completed" );
   ap_bsetflag( r->connection->client, B_EOUT, 1 );
   r->connection->aborted = 1;
     }
     return 0;
   }
 return written;
}

Thanks in advance
