sub-directories). This does B<NOT> detect symbolic links. Paths
containing C<../> will also be blocked.
+=item B<-a> I<alloc_size>
+
+Allocate value pointers in chunks of I<alloc_size>. This may improve CPU
+utilization on machines with slow C<realloc()> implementations, in
+exchange for slightly higher memory utilization. The default isE<nbsp>1.
+Do not set this more than the B<-w> value divided by your average RRD step
+size.

=head1 AFFECTED RRDTOOL COMMANDS
Shows any "pending" updates for a file, in order. The updates shown have
not yet been written to the underlying RRD file.
+=item B<FETCH> I<filename> I<CF> [I<start> [I<end>]]
+
+Calls C<rrd_fetch> with the specified arguments and returns the result in text
+form. If necessary, the file is flushed to disk first. The client side function
+C<rrdc_fetch> (declared in C<rrd_client.h>) parses the output and behaves just
+like C<rrd_fetch_r> for easy integration of remote queries.
+
=item B<FORGET> I<filename>
Removes I<filename> from the cache. Any pending updates B<WILL BE LOST>.
