.SH NAME
-\fBgetcchar\fP,
-\fBsetcchar\fP \- Get a wide character string and rendition from a \fBcchar_t\fP or set a \fBcchar_t\fP from a wide-character string
+\fB\%getcchar\fP,
+\fB\%setcchar\fP \-
+convert between a wide-character string and a \fIcurses\fR complex character string
.SH SYNOPSIS
\fB#include <curses.h>\fP
.sp
.B " const void *\fIopts\fP );"
.SH DESCRIPTION
.SS getcchar
-.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,
or
\fIcolor_pair\fP
.SS setcchar
-.PP
The \fBsetcchar\fP function initializes the location pointed to by \fIwcval\fP
by using:
.bP
The string may contain a single control character instead.
In that case, no nonspacing characters are allowed.
.SH EXTENSIONS
-.PP
X/Open Curses documents the \fIopts\fP argument as reserved for future use,
saying that it must be null.
-This implementation
+This implementation
uses that parameter in ABI 6 for the functions which have a color-pair
parameter to support extended color pairs:
.bP
and used to retrieve the color pair as an \fBint\fP value,
in addition retrieving it via the standard pointer to \fBshort\fP parameter.
.SH NOTES
-.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 VALUE
-.PP
When \fIwch\fP is a null pointer,
\fBgetcchar\fP returns the number of wide characters referenced by
\fIwcval\fP,
HP-UX\ 10 uses an opaque structure with 28 bytes,
which is large enough for the 6 \fBwchar_t\fP values.
.bP
-Solaris xpg4 curses uses a single array of 6 \fBwchar_t\fP values.
+Solaris \fIxpg4\fP curses uses a single array of 6 \fBwchar_t\fP values.
.PP
This implementation's \fBcchar_t\fP was defined in 1995
using \fB5\fP for the total of spacing and non-spacing characters
Unicode does not limit the (analogous) number of combining characters,
so some applications may be affected.
