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 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

ISO/ANSI C, UNIX98

Notes

The behaviour of wctrans depends on the LC_CTYPE category of the current locale.
