note: This is a resend, the first version vanished somewhere. hi list, i noticed that some locale(7) functions missing am propper man page. that page describes several functions like: iswalnum_l, iswalpha_l, iswblank_l, iswcntrl_l, iswdigit_l, iswgraph_l, islwower_l, iswprint_l, iswpunct_l, iswspace_l, iswupper_l, iswxdigit_l re, wh

Many applications will need to process its data using information from several different locales. Another application is the implementation of the internationalization handling in the upcoming ISO C++ standard library. To support this another set of the functions using locale data exist which have an additional argument. For example, .BR isupper () will not recognize an A-umlaut (\(:A) as an uppercase letter in the default .B "C" locale. .SH SEE ALSO .BR iswalnum (3), .BR iswalpha (3), .BR iswblank (3), .BR iswcntrl (3), .BR iswdigit (3), .BR iswgraph (3), .BR iswlower (3), .BR iswprint (3), .BR iswpunct (3), .BR iswspace (3), .BR iswupper (3), .BR iswxdigit (3), .BR setlocale (3), .BR toascii (3), .BR tolower (3), .BR toupper (3), .BR ascii (7), .BR locale (7) .SH COLOPHON This page is part of release 3.54 of the Linux .I man-pages project.
