 .SH RETURN VALUE
 
 On success, \fBflow_read\fR() returns the number of bytes read. On
-failure, a negative value indicating the error will be returned. If
-the number of bytes read equals count, a subsequent call to
-\fBflow_read\fR() should be performed to check if there were more
-bytes to read. This call to \fBflow_read\fR will return 0 if there was
-no more data and mark the end of the datagram.
