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

NOTES

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