.SH DESCRIPTION
-These routines return a string of \fBwchar_t\fR characters in \fIwstr\fR,
+These routines return a string of \fBwchar_t\fP wide characters in \fIwstr\fP,
extracted starting at the current cursor position in the named window.
-Attributes are stripped from the characters.
-The four functions with \fIn\fR as the last argument return a leading substring at most
-\fIn\fR bytes long (exclusive of the trailing NUL).
-Transfer stops at the end of the current line, or when \fIn\fR bytes have
-been stored at the location referenced by \fIwstr\fR.
.PP
-If the size \fIn\fR is not large enough to store a complete character,
+The four functions with \fIn\fP as the last argument return
+a leading substring at most \fIn\fP characters long
+(exclusive of the trailing NUL).
+Transfer stops at the end of the current line, or when \fIn\fP characters have
+been stored at the location referenced by \fIwstr\fP.
+.PP
+If the size \fIn\fP is not large enough to store a complete complex character,
an error is generated.
.SH NOTES
-Note that all routines except
-\fBwinnwstr\fR
+All routines except
+\fBwinnwstr\fP
may be macros.
-.SH RETURN VALUES
+.PP
+Each cell in the window holds a complex character (i.e., base-
+and combining-characters) together with attributes and color.
+These functions store only the wide characters,
+ignoring attributes and color.
+Use \fBin_wchstr\fP to return the complex characters from a window.
+.SH RETURN VALUE
All routines return

-upon failure. Upon
-successful completion, the *\fBinwstr\fR

+Upon
+successful completion, the *\fBinwstr\fP
routines return

+\fBOK\fP, and the *\fBinnwstr\fP
routines return the

+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
\fBwmove\fP, and return an error if the position is outside the window,
or if the window pointer is null.
