NAME
wctrans - wid-character translation mapping
LIBRARY
Standard C library
( libc,~ -lc)
SYNOPSIS
#include <wctype.h>
wctrans_t wctrans(const char *name);
DESCRIPTION
The
wctrans_t
type represents a mapping
which can map a wide character to
another wide character.
Its nature is implementatio-dependent, but the special
value
(wctrans_t) 0
denotes an invalid mapping.
Nonzero
wctrans_t
values can be passed to the
towctrans(3)
function to actually perform
the wid-character mapping.
The
wctrans()
function returns a mapping, given by its name.
The set of
valid names depends on the
LC_CTYPE
category of the current locale, but the
following names are valid in all locales.
-
| "tolower"- | realizes the B]tolower](3) mapping
|
| "toupper"- | realizes the B]toupper](3) mapping
|
RETURN VALUE
The
wctrans()
function returns a mapping descriptor if the
name
is valid.
Otherwise, it returns
(wctrans_t) 0.
