NAME
     wconv: towupper, towlower - translate characters

SYNOPSIS
     #include <ctype.h>
     #include <widec.h>
     #include <wctype.h>
     #include <xctype.h>
     wchar_t towupper(wchar_t c);
     wchar_t towlower(wchar_t c);

DESCRIPTION
     If the argument to towupper() represents a lower-case letter of the
     ASCII or supplementary code sets, the result is the corresponding
     upper-case letter. If the argument to towlower() represents an upper-
     case letter of the ASCII or supplementary code sets, the result is the
     corresponding lower-case letter.

     In the case of all other arguments, the return value is unchanged.

     The classification of upper-case and lower-case and the translation
     between them is based on the LC_CTYPE category of the current locale.
     The table which is used for translation is generated by wchrtbl(1M).

NOTES
     These functions can support either typedef unsigned short wchart or
     typedef long wchart conditionally, see mbchar(3W).

FILES
     /usr/include/mlx-loc/xctype.h
                     language dependent character classification and
                     conversion macros. The location of this file is
                     locale-specific, and it may not exist for some
                     locales. For example the japan locale uses
                     /usr/include/mlx-j/xctype.h.
