Question

Ok so i wrote a c++ websocket server took a while but i think i did good job for a intermediate programmer but have a question my friend suggested that i use hash_map from the namespace __gnu_cxx; it all builds fine and what not i just want to know say i need to change a users name in one of the user fields would it update just by doing this

_userslist[id].name = “BlaBla Bla”;

or would i need to replace the entire field with a copy but with name changed.

i would try it but when ever i take the server down all my members moan and moan so thought id ask here 🙂

Thanks
Dave

Most likely _userslist[id] will return a WinUser&, assuming _userslist is not const in this context. If name is a public member of WinUser that has an operator= that takes a const char * (or something const char * can convert into), then it will work.
