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.
