Hello, I have a question regarding creating composite key/specifying length for arrays while using multi_index container based on following structure. struct TestStruct { char firstKey[50]; char secondKeyPart[3]; uint32_t thirdKeyPart; ......Some other information.... }; Do I really read to specify this lengths for character arrays? If yes, how do I do that while specifying key parts as below? typedef multi_index_container < TestStruct, indexed_by< //non-unique as some subscribers might have more than one number hashed_unique< composite_key< TestStruct, member<TestStruct, char*, &TestStruct::firstKeyPart>, member<TestStruct, char*, &TestStruct::secondKeyPart>, member<TestStruct, uint32_t, &TestStruct::thirdKeyPart>, > >
TS;
Thanks
