This is Wide-characters? in view mode; [Up]
Date: Sun 16-Jan-1991 18:59:08 From: scott@sage.uchicago.edu (Scott Deerwester) Subject: Wide characters? I'm building an application that will use Unicode characters as the native text representation standard. And in stdlib.h are the following tantalizing function declarations: extern int mblen(const char *s, size_t n); extern int mbtowc(wchar_t *pwc, const char *s, size_t n); extern int wctomb(char *s, wchar_t wchar); extern size_t mbstowcs(wchar_t *pwcs, const char *s, size_t n); extern size_t wcstombs(char *s, const wchar_t *pwcs, size_t n); And in stddef.h is the following: typedef unsigned short wchar_t; Looks a *whole* lot like the ANSI C ($31.95 for the book; ack) definition, but I can't find a reference to these functions *anywhere*! I tried things like: find /usr/include -print | xargs grep wctomb grep -l wctomb /usr/lib/lib*.a No dice. Anybody have a clue what these functions are supposed to do? I'm *hoping* that they do some sort of mapping between something vaguely Unicode-like and something vaguely ASCII-like. (Hope springs eternal...) Does anybody know?
