Database loading</A>
</H3>
    The following set of functions provides an interface to database
    initialisation mechanisms:
    <PRE>
	int cl_loaddb(const char *filename, struct cl_node **root,
	unsigned int *signo);

	int cl_loaddbdir(const char *dirname, struct cl_node **root,
	unsigned int *signo);

	const char *cl_retdbdir(void);
</PRE>
    <code>cl_loaddb</code> loads selected database while <code>cl_loaddbdir</code>
    loads all databases from a <code>dirname</code> directory. <code>cl_retdbdir</code>
    returns a default (hardcoded) database directory path. After an
    initialisation an internal database representation will be saved
    under <code>root</code> (which must initially point to NULL) and a number of
    loaded signatures will be <B>added</B> <A NAME="tex2html36"
  HREF="footnode.html#foot339"><SUP>7</SUP></A> to <code>virnum</code>. You can eventually
    pass NULL if you don't care about a signature counter. Both <code>cl_loaddb</code>
    and <code>cl_loaddbdir</code> functions return 0 on success and a non-negative
    value on failure.
    <PRE>
	    ...
	    struct cl_node *root = NULL;
	    int ret, signo = 0;

	ret = cl_loaddbdir(cl_retdbdir(), &amp;root, &amp;signo);
</PRE>
