.SH DESCRIPTION
|
|
.PP
|
|
The \fBgetcchar\fP function gets a wide-character string
|
|
and rendition from a \fBcchar_t\fP argument.
|
|
When \fIwch\fP is not a null pointer,
|
|
the \fBgetcchar\fP function does the following:
|
|
.TP 5
|
|
-
|
|
Extracts information from a \fBcchar_t\fP value \fIwcval\fP
|
|
.TP 5
|
|
-
|
|
Stores the character attributes in the location pointed to by \fIattrs\fP
|
|
.TP 5
|
|
-
|
|
Stores the color-pair in the location pointed to by \fIcolor_pair\fP
|
|
.TP 5
|
|
-
|
|
Stores the wide-character string,
|
|
characters referenced by \fIwcval\fP, into the array pointed to by \fIwch\fP.
|
|
.PP
|
|
When
|
|
\fIwch\fP
|
|
is a null pointer, the
|
|
\fBgetcchar\fP
|
|
function does the following:
|
|
.TP 5
|
|
-
|
|
Obtains the number of wide characters pointed to by \fIwcval\fP
|
|
.TP 5
|
|
-
|
|
Does not change the data referenced by
|
|
\fIattrs\fP
|
|
or
|
|
\fIcolor_pair\fP
|
|
.PP
|
|
The \fBsetcchar\fP function initializes the location pointed to by \fIwcval\fP
|
|
by using:
|
|
.TP 5
|
|
-
|
|
The character attributes in
|
|
\fIattrs\fP
|
|
.TP 5
|
|
-
|
|
The color pair in
|
|
\fIcolor_pair\fP
|
|
.TP 5
|
|
-
|
|
The wide-character string pointed to by \fIwch\fP.
|
|
The string must be L'\\0' terminated,
|
|
contain at most one spacing character,
|
|
which must be the first.
|
|
.IP
|
|
Up to \fBCCHARW_MAX\fP-1 nonspacing characters may follow.
|
|
Additional nonspacing characters are ignored.
|
|
.IP
|
|
The string may contain a single control character instead.
|
|
In that case, no nonspacing characters are allowed.
|
|
.SH NOTES
|
|
.PP
|
|
The \fIopts\fP argument is reserved for future use.
|
|
Currently, an application must provide a null pointer as \fIopts\fP.
|
|
.PP
|
|
The \fIwcval\fP argument may be a value generated by a call to
|
|
\fBsetcchar\fP or by a function that has a \fBcchar_t\fP output argument.
|
|
If \fIwcval\fP is constructed by any other means, the effect is unspecified.
|
|
.SH RETURN VALUES
|
|
.PP
|
|
When \fIwch\fP is a null pointer,
|
|
\fBgetcchar\fP returns the number of wide characters referenced by
|
|
\fIwcval\fP.
|
|
.PP
|
|
When \fIwch\fP is not a null pointer,
|
|
\fBgetcchar\fP returns \fBOK\fP upon successful completion,
|
|
and \fBERR\fP otherwise.
|
|
.PP
|
|
Upon successful completion, \fBsetcchar\fP returns \fBOK\fP.
|
|
Otherwise, it returns \fBERR\fP.
