.SH DESCRIPTION
.sp
.LP
The \fBinwstr()\fR and \fBwinwstr()\fR functions retrieve a wide character
string (without attributes) starting at the current cursor position  of the
\fBstdscr\fR window and window \fIwin\fR, respectively, and ending at the right
margin. The \fBmvinwstr()\fR and \fBmvwinwstr()\fR functions retrieve a wide
character string located at the position indicated by the \fIx\fR (column) and
\fIy\fR (row) parameters (the former in the \fBstdscr\fR window; the latter  in
window \fIwin\fR).
.sp
.LP
The \fBinnwstr()\fR, \fBwinnwstr()\fR, \fBmvinnwstr()\fR, and
\fBmvwinnwstr()\fR functions retrieve at most \fIn\fR characters from the
window \fBstdscr\fR and \fIwin\fR, respectively.  The former two functions
retrieve the string starting at the current cursor position; the latter two
commands return the string, starting at the position  specified by the \fIx\fR
and \fIy\fR parameters.
.sp
.LP
All these functions store the retrieved string in the object pointed to by
\fIwstr\fR. They only store complete wide characters. If the area pointed to by
\fIwstr\fR is not large enough to hold at least one character, these functions
fail.
.sp
.LP
Only the character portion of the character/rendition pair is returned.  To
return the complete character/rendition pair, use \fBwin_wchstr\fR(3XCURSES).
.SH RETURN VALUES
.sp
.LP
On success, the \fBinwstr()\fR, \fBmvinwstr()\fR, \fBmvwinwstr()\fR, and
\fBwinwstr()\fR functions return \fBOK\fR. Otherwise, they return \fBERR\fR.
.sp
.LP
On success, the \fBinnwstr()\fR, \fBmvinnwstr()\fR, \fBmvwinnwstr()\fR, and
\fBwinnwstr()\fR functions return the number of characters read into the
string. Otherwise, they return \fBERR\fR.
.SH ERRORS
