Description:
| The list of available WLAN networks and their instant signal strength can be obtained by using the interfaces provided by the Connection Monitor Server API.
Here is an example of how the API can be used:
#include <rconnmon.h>
void CWlanTest:: ListNetworksAndSignalL(CDesCArraySeg& aNetworks)
{
_LIT(KNetInfo, "Network: %S\tSignal: %d");
TBuf<32> netName;
TBuf<100> line;
RConnectionMonitor monitor;
TPckgBuf<TConnMonNetworkNames> pkgNetworks;
// establish connection with the monitor server
monitor.ConnectL();
// prepare leave clean-up
CleanupClosePushL(monitor);
TRequestStatus status;
// get the list of available networks
monitor.GetPckgAttribute(EBearerIdWLAN, 0, KNetworkNames, pkgNetworks, status);
// suspend thread until the info is retrieved
// production code should use active objects
User::WaitForRequest( status ) ;
// leave if the asynchronous method returned an error
User::LeaveIfError(status.Int());
// reset networks list
aNetworks.Reset();
// add retrieved networks to the list
for(TUint i=0; i<pkgNetworks().iCount; i++)
{
netName.Copy(pkgNetworks().iNetwork[i].iName);
line.Format(KNetInfo, &netName, pkgNetworks().iNetwork[i].iSignalStrength);
aNetworks.AppendL(line);
}
// close server session
CleanupStack::PopAndDestroy(&monitor);
}
