All of those would hang Emacs. It makes more sense to asynchronously ask something like ping to do it and check back on that. I'm sure that there is a canonical way for Emacs to check if it has an Internet connection, and I even remember reading a conversation about this issue on emacs-devel... who knows how long ago that was. -- "Cut your own wood and it will warm you twice" _______________________________________________ Emms-help mailing list [email protected] https://lists.gnu.org/mailman/listinfo/emms-help
