If \fIc\fP is EOF or not a valid multibyte sequence of length 1, +the \fBbtowc\fP function returns WEOF. +.SH "RETURN VALUE" +The \fBbtowc\fP function returns the wide character converted from the single +byte \fIc\fP. If \fIc\fP is EOF or not a valid multibyte sequence of length 1, +it returns WEOF. +.SH "CONFORMING TO" +ISO/ANSI C, UNIX98 +.SH "SEE ALSO" +.BR mbtowc (3) +.SH NOTES +The behaviour of \fBbtowc\fP depends on the LC_CTYPE category of the +current locale. +.PP +This function should never be used. It does not work for encodings which have +state, and unnecessarily treats single bytes differently from multibyte +sequences. Use the function \fBmbtowc\fP instead. |
