Re: [Dev-C++] Optimizing using the STL

[David M. <ci...@ya...>]

Hmm,

Some interesting comments. (I know I need to increment the
iterator, I
forgot that when I sent this e-mail). So far the only
optimization that
would be applicable is the passing by refrence. This
program is
multi-threaded so even though I could use mutexes, etc. to
prevent the
string from changing between calls to write_to_player I
would rather not
have that headache. If you are wondering I plan to put the
map in a
Read-write mutex (the only time that map changes is when a
player logs in or
logs out).

Thanks for all your comments.
