\fBint inchnstr(chtype *chstr, int n);\fR
.SH DESCRIPTION
These routines return a NULL-terminated array of \fBchtype\fR quantities,
starting at the current cursor position in the named window and ending at the
-right margin of the window. The four functions with \fIn\fR as
+right margin of the window.
+The four functions with \fIn\fR as
the last argument, return a leading substring at most \fIn\fR characters long
(exclusive of the trailing (chtype)0).
Constants defined in \fB<curses.h>\fR can be used with the \fB&\fR (logical
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
+X/Open Curses defines no error conditions.
+In this implementation:
+.bP
+If the \fIwin\fP parameter is null, an error is returned,
+.bP
+If the \fIchstr\fP parameter is null, an error is returned,
+.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.
