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.
