21 !!DESCRIPTION

23
24 The __wctrans_t__ type represents a mapping which can map
25 a wide character to another wide character. Its nature is
26 implementation dependent, but the special value
27 ''(wctrans_t)0'' denotes an invalid mapping. Nonzero
28 __wctrans_t__ values can be passed to the
29 __towctrans__ function to actually perform the wide
30 character mapping.
31
32
33 The __wctrans__ function returns a mapping, given by its
34 name. The set of valid names depends on the LC_CTYPE
35 category of the current locale, but the following names are
36 valid in all locales.

44 The __wctrans__ function returns a mapping descriptor if
45 the ''name'' is valid. Otherwise it returns
46 ''(wctrans_t)0''.
