SYNOPSIS
     ##iinncclluuddee <>

     wintt
     ttoowwuuppppeerr(wintt wc);

DESCRIPTION
     The ttoowwuuppppeerr() function converts a lower-case letter to the corresponding
     upper-case letter.

     While the ttoowwuuppppeerr() function uses the current locale, the ttoowwuuppppeerrll()
     function may be passed a locale directly. See xlocale(3) for more infor-
     mation.

RETURN VALUES
     If the argument is a lower-case letter, the ttoowwuuppppeerr() function returns
     the corresponding upper-case letter if there is one; otherwise the argu-
     ment is returned unchanged.

STANDARDS     The ttoowwuuppppeerr() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
