wctype.h \- wide-character classification and mapping utilities

.SH SYNOPSIS
|

.LP
|
|
\fB#include <wctype.h>\fP
|
|
.SH DESCRIPTION
|
|
.LP
|
|
Some of the functionality described on this reference page extends
|
|
the ISO\ C standard. Applications shall define
|
|
the appropriate feature test macro (see the System Interfaces volume
|
|
of IEEE\ Std\ 1003.1-2001, Section 2.2, The Compilation Environment)
|
|
to enable the visibility of these symbols in this
|
|
header.
|
|
.LP
|
|
The \fI<wctype.h>\fP header shall define the following types:
|
|
.TP 7
|
|
\fBwint_t\fP
|
|
As described in \fI<wchar.h>\fP .
|
|
.TP 7
|
|
\fBwctrans_t\fP
|
|
A scalar type that can hold values which represent locale-specific
|
|
character mappings.
|
|
.TP 7
|
|
\fBwctype_t\fP
|
|
As described in \fI<wchar.h>\fP .
|
|

The following shall be declared as functions and may also be defined
|
|
as macros. Function prototypes shall be provided.

.LP
|
|
The \fI<wctype.h>\fP header shall define the following macro name:
|
|
.TP 7
|
|
WEOF
|
|
Constant expression of type \fBwint_t\fP that is returned by several
|
|
MSE functions to indicate end-of-file.
|
|
.sp
|
|
.LP
|
|
For all functions described in this header that accept an argument
|
|
of type \fBwint_t\fP, the value is representable as a
|
|
\fBwchar_t\fP or equals the value of WEOF. If this argument has any
|
|
other value, the behavior is undefined.
|
|
.LP
|
|
The behavior of these functions shall be affected by the \fILC_CTYPE\fP
|
|
category of the current locale.
|
|
.LP
|
|
Inclusion of the \fI<wctype.h>\fP header may make visible all symbols
|
|
from the headers \fI<ctype.h>\fP, \fI<stdarg.h>\fP, \fI<stddef.h>\fP,
|
|
\fI<stdio.h>\fP, \fI<stdlib.h>\fP, \fI<string.h>\fP, \fI<time.h>\fP,
|
|
and \fI<wchar.h>\fP.
