<code>cl_retdbdir()</code> returns the default (hardcoded) path to the directory
|
|

|
|
with ClamAV databases.
|
|
|
|
|
<code>cl_load()</code> loads a single database file or all databases from a
|
|
|
|
|
given directory (when <code>path</code> points to a directory). The second
|
|
|
|
|
argument is used for passing in the pointer to the engine that should
|
|
|
|
|
be previously allocated with <code>cl_engine_new()</code>. A number of loaded
|
|
|
|
|
signatures will be <SPAN CLASS="textbf">added</SPAN> to <code>signo</code> <A NAME="tex2html20"
|
|
|
|
|
HREF="footnode.html#foot325"><SUP><SPAN CLASS="arabic">8</SPAN></SUP></A>. The last argument can
|
|
|
|
|
pass the following flags:

failure.
