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.

STANDARDS

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