This is not an argument. The fact that you may not do it does not imply that you should be careless. Maintaining such simple rules helps in case you ever decide to do it, but it doesn't hurt if you don't. Moreover, reentrance is a requirement not only for that but for any form of parallel processing where a function may be called more than once. Future changes in the code may trigger hard to track bugs where you don't expect them because at that point you won't remember that you need to fix this as well. And in this particular case I hardly see any reason/benefit for/from a global variable. -- Dan _______________________________________________ Devel mailing list Devel@lists.openser.org http://lists.openser.org/cgi-bin/mailman/listinfo/devel
