wctrans(3)               Library Functions Manual              wctrans(3)

NAME         top

       wctrans - wide-character translation mapping

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <wctype.h>

       wctrans_t wctrans(const char *name);

DESCRIPTION         top

       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 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         top

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