wctrans
NAME
wctrans - wide-character translation mapping
SYNOPSIS
#include <wctype.h> I 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 implementation dependent, but the special
value (wctrans_t) 0 denotes an invalid mapping.
Nonzero wctrans_t
values can be passed to the
R towctrans ()
function to actually perform
the wide-character mapping.
The
R 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 tolower(3) mapping "toupper" - realizes the toupper(3) mapping
RETURN VALUE
The
R wctrans ()
function returns a mapping descriptor if the name
is valid.
Otherwise it returns (wctrans_t) 0.
CONFORMING TO
C99.
NOTES
The behavior of
R wctrans ()
depends on the
LC_CTYPE
category of the
current locale.
