This tutorial describes how to get the call waiting status information with the telephony API for applications.
#include <e32base.h> #include <Etel3rdParty.h> class CClientApp : public CActive { private: CTelephony* iTelephony; CTelephony::TCallWaitingSupplServicesV1 iCallWaitingSupplServicesV1; CTelephony::TCallWaitingSupplServicesV1Pckg iCallWaitingSupplServicesV1Pckg; public: CClientApp(CTelephony* aTelephony); void SomeFunction(); private: /* These are the pure virtual methods from CActive that MUST be implemented by all active objects */ void RunL(); void DoCancel(); }; CClientApp::CClientApp(CTelephony* aTelephony) : CActive(EPriorityStandard), iTelephony(aTelephony), iCallWaitingSupplServicesV1Pckg(iCallWaitingSupplServicesV1) { //default constructor } void CClientApp::SomeFunction() { iTelephony->GetCallWaitingStatus(iStatus, iCallWaitingSupplServicesV1Pckg); SetActive(); } void CClientApp::RunL() { if(iStatus==KErrNone) { CTelephony::TSupplServiceStatus callWaitingStatus = iCallWaitingSupplServicesV1.iCallWaiting; } } void CClientApp::DoCancel() { iTelephony->CancelAsync(CTelephony::EGetCallWaitingStatusCancel); }
