C++ TResourceReader::ReadTPtrC16方法代码示例

/**
   @SYMTestCaseID T-RApaLsSessionTestStep-TestServiceDiscovery8L
  
   @SYMPREQ 538
  
   @SYMTestCaseDesc Test for the functionality of GetAppServiceOpaqueDataLC, particularly in the case 
   where an app offers two services with the same uid but different opaque data
   
   @SYMTestPriority 
  
   @SYMTestStatus Implemented
   
   @SYMTestActions Call GetAppServiceOpaqueDataLC with two parameters: an app uid and a service uid
   on z: drive.\n
   API Calls:\n	
   RApaLsSession::GetAppServiceOpaqueDataLC(TUid aAppUid, TUid aServiceUid) const
   
   @SYMTestExpectedResults Returns an array of TApaAppServiceInfo objects. Each TApaAppServiceInfo object 
   contains the same service uid but different opaque data. The returned data should be the same as that 
   defined in the registration files.
