SYNOPSIS

     #include <wctype.h>

     wint_t
     towupper(wint_t wc);

     #include <xlocale.h>

     wint_t
     towupper_l(wint_t wc, locale_t 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 towupper_l()
     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'').
