TOWLOWER(3)						   BSD Library Functions Manual 					       TOWLOWER(3)

NAME
     towlower, towlower_l -- upper case to lower case letter conversion (wide character version)

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <wctype.h>

     wint_t
     towlower(wint_t wc);

     #include <wctype.h>
     #include <xlocale.h>

     wint_t
     towlower_l(wint_t wc, locale_t loc);

DESCRIPTION
     The towlower() function converts an upper-case letter to the corresponding lower-case letter.

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

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

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