TOWUPPER(3)		 BSD Library Functions Manual		   TOWUPPER(3)

NAME
     towupper, towupper_l — lower case to upper case letter conversion (wide
     character version)

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <wctype.h>

     wint_t
     towupper(wint_t wc);

     #include <wctype.h>
     #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.

     Although the towupper() function uses the current locale, the
     towupper_l() function may be passed a locale directly. See xlocale(3) for
     more information.

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.

SEE ALSO
     iswupper(3), toupper(3), towlower(3), wctrans(3), xlocale(3)

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