.In wctype.h

.Sh DESCRIPTION
|
||||
The
|
||||
.Fn wctype
|
||||
function returns a value of type
|
||||
.Vt wctype_t
|
||||
which represents the requested wide character class and
|
||||
may be used as the second argument for calls to
|
||||
.Fn iswctype .
|
||||
.Pp
|
||||
The following character class names are recognised:
|
||||
.Bl -column -offset indent ".Li alnum" ".Li cntrl" ".Li phonogram" ".Li print" ".Li special"
|
||||
.It Li alnum Ta Li cntrl Ta Li ideogram Ta Li print Ta Li special
|
||||
.It Li alpha Ta Li digit Ta Li lower Ta Li punct Ta Li upper
|
||||
.It Li blank Ta Li graph Ta Li phonogram Ta Li space Ta Li xdigit
|
||||
.El
|
||||
.Pp
|
||||
The
|
||||
.Fn iswctype
|
||||
function checks whether the wide character
|
||||

|
||||

|
||||
.Fa charclass .
|
||||
.Sh RETURN VALUES

||||
.Fa charclass
|
||||
is zero.
|
||||
.Pp
|
||||
The
|
||||
.Fn wctype
|
||||
function returns 0 if
|
||||
.Fa property
|
||||
is invalid, otherwise it returns a value of type
|
||||
.Vt wctype_t
|
||||
that can be used in subsequent calls to
|
||||
.Fn iswctype .
