[Howto]在Symbian3rd上获取短消息信息

 ///------------------------------------------------------
///						短消息

///STEP1 创建会话
CMsvSession* iSession = CMsvSession::OpenAsyncL(/*OBSERVER*/);

///STEP2 通过会话得到根节点MsvEntry。短消息的存储是一个树形结构。
CMsvEntry* root = iSession->GetEntryL(KMsvRootIndexEntryId);

///STEP3 通过访问该树形结构，遍历所有短消息
CMsvEntrySelection* rootChildren = root->ChildrenL();
for (int i = 0; i < rootChildren->Count(); ++i)
{
	CMsvEntry* sub = root->GetEntryL(rootChildren[i]);

	if (sub)
	{
		///STEP4 递归处理

		//... 如果sub是最底层短消息节点，处理。负责递归遍历sub孩子列表

		delete sub;
		sub = NULL;
	}
}
delete rootChildren;
rootChildren = NULL;

delete root;
root = NULL;

delete iSession;
iSession = NULL;
