 .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 defines no error conditions.
-In this implementation,
-if the window parameter is null or the str parameter is null,
-a zero is returned.

+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.
