S60 3rd Edition

S60 3rd Edition, FP1

详细描述

现在我们可以通过Phone Client Extension API（其为S60第三版扩展插件包的一部分）来控制手机麦克风无声或取消无声。

Extensions plug-in package for S60 3rd Edition SDK for Symbian OS, for C++, MR

Extensions plug-in package for S60 3rd Edition SDK for Symbian OS, for C++, supporting FP1

解决方案

下列代码显示了通过加载PhoneClientExt这个Dll，来构造一个command handler(CPhCltCommandHandler)以设置无声或取消无声。

需要功能：WriteDeviceData

/*** Header file ***/
 
    #include <RPhCltServer.h>   // link against PhoneClient.lib
 
    #include <PhCltExt.h>       // link against PhoneClientExt.lib
 
    ...
 
 
 
    RPhCltServer iPhoneClientServer;
 
    RLibrary iLibrary;
 
    CPhCltCommandHandler* iPhCommandHandler;
 
    /*** Source file ***/
 
    _LIT(KPhoneCltExDllName, "PhoneClientExt.dll");
 
    User::LeaveIfError( iPhoneClientServer.Connect() );
 
    User::LeaveIfError( iLibrary.Load(KPhoneCltExDllName) );
 
    TInt res = iLibrary.Lookup(1)();
 
    CPhCltExtFactory* phCltExtFactory = reinterpret_cast<CPhCltExtFactory*>( res );
 
    iPhCommandHandler = phCltExtFactory->CPhCltCommandHandlerLD();
 
    User::LeaveIfError( iPhCommandHandler->Open( iPhoneClientServer ) );
 
    // Mute the microphone. This should be done inside an active object
 
    // (a class derived from CActive)
 
    iPhCommandHandler->MuteMicrophone( iStatus, ETrue );
 
    SetActive();
