FUNCTION
<<towctrans>>, <<towctrans_l>>---extensible wide-character translation
INDEX
towctrans
INDEX
towctrans_l
SYNOPSIS
#include <wctype.h>
wint_t towctrans(wint_t <[c]>, wctrans_t <[w]>);
#include <wctype.h>
wint_t towctrans_l(wint_t <[c]>, wctrans_t <[w]>, locale_t <[locale]>);
DESCRIPTION
<<towctrans>> is a function which converts wide characters based on
a specified translation type <[w]>. If the translation type is
invalid or cannot be applied to the current character, no change
to the character is made.
<<towctrans_l>> is like <<towctrans>> but performs the function based on the
locale specified by the locale object locale. If <[locale]> is
LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined.
RETURNS
<<towctrans>>, <<towctrans_l>> return the translated equivalent of <[c]>
when it is a valid for the given translation, otherwise, it returns the
input character. When the translation type is invalid, <<errno>> is
set to <<EINVAL>>.
PORTABILITY
<<towctrans>> is C99.
<<towctrans_l>> is POSIX-1.2008.
No supporting OS subroutines are required.
