WCTRANS(3) Linux Programmer's Manual WCTRANS(3)NAMEwctrans - 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 implementation dependent, but
the special value (wctrans_t) 0 denotes an invalid mapping. Nonzero
wctrans_t values can be passed to the towctrans() 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.

The behaviour of wctrans() depends on the LC_CTYPE category of the cur‐
rent locale.
