WCTRANS(3)                                          Linux Programmer's Manual                                         WCTRANS(3)



NAME
       wctrans - wide-character translation mapping

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 imple-
       mentation-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 wide-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 tolower(3) mapping
         "toupper" - realizes the toupper(3) mapping

RETURN VALUE
       The wctrans() function returns a mapping descriptor if the name is valid.  Otherwise it returns (wctrans_t) 0.

CONFORMING TO
       C99.

NOTES
       The behavior of wctrans() depends on the LC_CTYPE category of the current locale.
