<H1 CLASS="chapter"><A NAME="htoc258">Chapter26</A>The dbm library: access to NDBM databases</H1><P>The <TT>dbm</TT> library provides access to NDBM databases under Unix.
NDBM databases maintain key/data associations, where both the key and
the data are arbitrary strings. They support fairly large databases
(several gigabytes) and can retrieve a keyed item in one or two file
system accesses. Refer to the Unix manual pages for more information.</P><BLOCKQUOTE CLASS="quote"><FONT COLOR=purple>Unix:</FONT>
Programs that use the <TT>dbm</TT> library must be linked as follows:
<PRE>
ocamlc <I>other options</I> dbm.cma <I>other files</I>
ocamlopt <I>other options</I> dbm.cmxa <I>other files</I>
</PRE>
For interactive use of the <TT>dbm</TT> library, do:
<PRE>
ocamlmktop -o mytop dbm.cma
./mytop
</PRE>
</BLOCKQUOTE><P>
or (if dynamic linking of C libraries is supported on your platform),
start <TT>ocaml</TT> and type <TT>#load "dbm.cma";;</TT>.</P><BLOCKQUOTE CLASS="quote"><FONT COLOR=purple>Windows:</FONT>
This library is not available.
