NAME
     towupper, towupperl -- lower case to upper case letter conversion (wide
     character version)

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##include <>

     wintt
     towupper(wintt wc);

     ##include <>

     wintt
     towupperl(wintt wc, localet loc);

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

     While the towupper() function uses the current locale, the towupperl()
     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 towupper() function returns
     the corresponding upper-case letter if there is one; otherwise the argu-
     ment is returned unchanged.

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