NAME

6       wctrans - wide-character translation mapping
7

SYNOPSIS

9       #include <wctype.h>
10
11       wctrans_t wctrans(const char *name);
12

DESCRIPTION

14       The  wctrans_t type represents a mapping which can map a wide character
15       to another wide character.  Its nature is implementation-dependent, but
16       the  special  value (wctrans_t) 0 denotes an invalid mapping.  Non-zero
17       wctrans_t values can be passed to the towctrans(3) function to actually
18       perform the wide-character mapping.
19
20       The  wctrans()  function returns a mapping, given by its name.  The set
21       of valid names depends on the LC_CTYPE category of the current  locale,
22       but the following names are valid in all locales.
23         "tolower" - realizes the tolower(3) mapping
24         "toupper" - realizes the toupper(3) mapping
25

RETURN VALUE

27       The  wctrans()  function  returns  a  mapping descriptor if the name is
28       valid.  Otherwise it returns (wctrans_t) 0.
29

CONFORMING TO

NOTES

34       The behavior of wctrans() depends on the LC_CTYPE category of the  cur‐
35       rent locale.
