Thanks. This worked for me. Full code is as below.
outField = outModDesc->FindFieldByName(tmp_name);
const google::protobuf::Descriptor* tmpDesc = outField->message_type();
std::string subMsgType = tmpDesc->name();
std::string subFullMsgType = tmpDesc->full_name();
std::cout << " Type:" << subMsgType
<< "new Type" << newMsgType << std::endl;
Output:
========
Type:ConfigMsg
Full Type:frrcfg.ConfigMsg
Thanks,
Kiran.
