Uh? isalpha() not portable? Its behaviour was defined by ANSI C89, as well as that of isspace(), isupper(), and a few more functions in ctype.h. Maybe you hit a specific bug of a specific implementation, but if you can't even use the functions defined in ANSI C, you'd better program in assembly :) HND KatolaZ -- [ ~.,_ Enzo Nicosia aka KatolaZ - GLUGCT -- Freaknet Medialab ] [ "+. katolaz [at] freaknet.org --- katolaz [at] yahoo.it ] [ @) http://kalos.mine.nu --- Devuan GNU + Linux User ] [ @@) http://maths.qmul.ac.uk/~vnicosia -- GPG: 0B5F062F ] [ (@@@) Twitter: @KatolaZ - skype: katolaz -- github: KatolaZ ] _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
