| Well, I guess we might as well change the API, since everyone else does. Unless | someone comes up with a bettter idea, of course :) | | -Joe The API should not change. There is already enough descrepency between UNIXs to warrant programs like autoconf, we should not introduce another. We should introduce a gethostbyaddr_r function, which shouldn't be all that though to implement. From the code that I looked at today, the problems lie inside of glibc. It declares globally a few static variables that are used by the gethost* functions. Obviously in a threaded environment, this is bad. A nice fix would be to get rid of those variables entirely. A quicker fix would be just to enclose those global variables in mutexes. Personally, I like the nicer fix better, which will (unfortunately) involve rewriting most of the frontends to the res_* functions. If no one has any objections, I'd like to start on this tomorrow.
