c++ - Combine multiple variables to send as a udp packet -


i need send packet of data on udp connection in c++. first message need send built of 2 32 bit integers , 64 bit integer. best way combine multiple variable types 1 block of data ready sending on udp connection?

it depends on requirements network. care endianness? if do, should use not serialisatioin, safe 1 in regards endianness.

generally, each class/struct sendable through network should have special methods or overloaded operators stream them in , out. you'll have use macros/functions hton/ntoh streaming primitive types eg int, int64, float, double etc.

upd: if network endpoint applications run on different platforms/compilers, may have different sizes of int, long, short etc. when serialising, you'll have convert integers predefined types sizes guaranteed same on supported platforms.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
