All, I have a design sinerio. I have different struct (C structures) having different data's but NO similarities between struct and each struct does different operations. The struct for example are - struct Apple { int A; char B; long C; double d; .. ..}; struct Orange { char A; int B; unsigned int C; long d; .. }; and maybe few more. Above few struct data members have dynamic data and other members have fixed/hardcoded datas. The complete struct is send as a buffer to a remote machine through native send()/read() API calls which has been successfully implemented. Please note this data as tested were hard coded or completely static but didn't had combination of dynamic/real and static data.. Now such operations (viz different or repeated) with ONE/MULTIPLE SET of data could be many as 1000, I wish now to send complete operations to remote machine, get a ACK from it and work on this struct data with modification/cancellation/reject/etc operations. One way could be to work with something similar - struct Apple { ... ..}; vector <Apple> data; data.insert (begin();end()) --- But, I have few questions - 1. I can have "std::map<string, vector>" and send this data as native send(). Latter read/recv() with string. Am I correct as I would have multiple operations? 2. I do wish to maintain synchronisation using Boost::lockfree mechanism latter? 3. Any other techniques? Thanks.
