Retrieve channel metadata

Copy link

You can retrieve channel metadata by creating a List of keys to retrieve and passing it as an argument to a parameter in the GetMetaData() method. A std::map<std::wstring, std::wstring> will return key-value items through the Handler function.

std::vector<std::wstring> keys;
keys.push_back(L"key1");
keys.push_back(L"key2");

channel->GetMetaData(keys, [](const std::map<std::wstring, std::wstring>& meta_data, SBDError* error) {
    if (error != nullptr) {
        // Handle error.
        return;
    }
});
