преобразование расширенных символов (wide-character translation mapping)
Имя (Name)
wctrans - wide-character translation mapping
Синопсис (Synopsis)
#include <wctype.h>
wctrans_t wctrans(const char *name);
Описание (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(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
Возвращаемое значение (Return value)
The wctrans() function returns a mapping descriptor if the name
is valid. Otherwise, it returns (wctrans_t) 0.
