.SH "DESCRIPTION"
.PP
\fBseq_open\fR sets \fIfile\fR, associating it with a sequence described
by \fIop\fR\&.  \fIop\fR->\fBstart\fR sets the iterator up and returns the first
element of sequence. \fIop\fR->\fBstop\fR shuts it down.  \fIop\fR->\fBnext\fR
returns the next element of sequence.  \fIop\fR->\fBshow\fR prints element
into the buffer.  In case of error ->\fBstart\fR and ->\fBnext\fR return
ERR_PTR(error).  In the end of sequence they return NULL\&. ->\fBshow\fR
returns 0 in case of success and negative number in case of error.
