.SH SYNOPSIS
\fB#include <curses.h>\fR
-
+.sp
\fBint inchstr(chtype *chstr);\fR
.br
\fBint inchnstr(chtype *chstr, int n);\fR
(exclusive of the trailing (chtype)0).
Constants defined in \fB<curses.h>\fR can be used with the \fB&\fR (logical
AND) operator to extract the character or the attribute alone from any position
-in the \fIchstr\fR [see curs_inch(3X)].
+in the \fIchstr\fR [see \fBcurs_inch\fR(3X)].
.SH RETURN VALUE
All routines return the integer \fBERR\fR upon failure and an integer value
other than \fBERR\fR upon successful completion (the number of characters
retrieved, exclusive of the trailing 0).
+.PP
+No error conditions are defined.
+If the \fIchstr\fP parameter is null,
+no data is returned,
+and the return value is zero.
+.PP
+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.
.SH NOTES
Note that all routines except \fBwinchnstr\fR may be macros. SVr4 does not
-document whether the result string is 0-terminated; it does not document
+document whether the result string is zero-terminated; it does not document
whether a length limit argument includes any trailing 0; and it does not
document the meaning of the return value.
.SH PORTABILITY
that the successful return of the functions is \fBOK\fR.
