14 The wctrans_t type represents a mapping which can map a wide character
15 to another wide character. Its nature is implementation dependent, but
16 the special value (wctrans_t) 0 denotes an invalid mapping. Nonzero
17 wctrans_t values can be passed to the towctrans() function to actually
18 perform the wide character mapping.

20 The wctrans() function returns a mapping, given by its name. The set of
21 valid names depends on the LC_CTYPE category of the current locale, but
22 the following names are valid in all locales.
23 "tolower" - realizes the tolower(3) mapping
24 "toupper" - realizes the toupper(3) mapping
25
27 The wctrans() function returns a mapping descriptor if the name is
28 valid. Otherwise it returns (wctrans_t)0.
