wctrans - wide character translation mapping
Návod, kniha: Linux Programmer's Manual
#include <wctype.h>
wctrans_t wctrans(const char *name);
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
The
wctrans function returns a mapping descriptor if the
name is
valid. Otherwise it returns
(wctrans_t)0.
ISO/ANSI C, UNIX98
wctrans(3)
The behaviour of
wctrans depends on the LC_CTYPE category of the current
locale.
