 .SH DESCRIPTION
 These routines return a string of characters in \fIstr\fR, extracted starting
 at the current cursor position in the named window.
-Attributes are stripped from the characters.  The four
+Attributes are stripped from the characters.
+The four
 functions with \fIn\fR as the last argument return a leading substring at most
 \fIn\fR characters long (exclusive of the trailing NUL).
 .SH RETURN VALUE
 All of the functions return \fBERR\fR upon failure,
 or the number of characters actually read into the string.
+.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.
 .SH NOTES
 Note that all routines except \fBwinnstr\fR may be macros.
 .SH PORTABILITY
-The XSI Curses
-error conditions \fBEILSEQ\fR and \fBEILOVERFLOW\fR associated with
