I guess I favor an opt-in rather than the current opt-out strategy for plexit(). However it is true that both are going to land you in the same place, unless you have a special error handler your program is going to crash with a (possibly cryptic) error message. At this point I agree with you that adding an error flag to the stream which the user can check is the way to go. Changing all the functions in all the bindings would be extremely disruptive. Cairo and GTK are C I believe, it might be worth a look to see how they handle this. -Hazen ------------------------------------------------------------------------------ _______________________________________________ Plplot-devel mailing list Plplot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/plplot-devel
