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="tex2html38"
HREF="footnode.html#foot343"><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(), &root, &signo);
</PRE>
