wctrans(3) — Linux manual pages

Linux manual pages	Section 3: Subroutines

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(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

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

CONFORMING TO

C99.

NOTES

The behavior of wctrans() depends on the LC_CTYPE category of the current locale.
