Code snippet

The following code can be used to monitor on Internet connection and display the process UID and name which is trying to connect:

  RSocketServ socketServ;
RConnection connection;
TConnectionInfoBuf connInfo;
TUint count;
TConnEnumArgBuf enumArgBuf;
TConnMonClientEnum aClientEnum;
TInt err;
TConnGetClientInfoArgBuf clientInfoBuf;
socketServ.Connect();
connection.Open( socketServ );
 
// Enumerates currently active interfaces
if( connection.EnumerateConnections(count) == KErrNone )
{
for ( TUint j=1; j<=count; j++ )
{
enumArgBuf().iIndex = j;
if(connection.Control( KCOLConnection,
KCoEnumerateConnectionClients,
enumArgBuf ) == KErrNone )
{
for ( TUint i=1; i <= enumArgBuf().iCount; i++ )
{
clientInfoBuf().iIndex = i;
err = connection.Control( KCOLConnection,
KCoGetConnectionClientInfo,
clientInfoBuf );
if ( err != KErrNone )
{
continue;
}
 
TInt uid = clientInfoBuf().iClientInfo.iUid.iUid;
RProcess process;
process.Open(clientInfoBuf().iClientInfo.iProcessId );
process.Name();
TBuf<16> buf;
buf.AppendNum( uid, EHex );
CEikonEnv::InfoWinL( buf, process.Name() );
process.Close();
}
}
}
}
 
connection.Close();
socketServ.Close();
