Database loading</A>
</H3>
The following set of functions provides an interface for loading
the virus database:
<PRE>
const char *cl_retdbdir(void);
int cl_load(const char *path, struct cl_engine *engine,
unsigned int *signo, unsigned int options);
</PRE>
<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 <B>added</B> to <code>signo</code> <A NAME="tex2html22"
HREF="footnode.html#foot352"><SUP>10</SUP></A>. The last argument can
pass the following flags:
<UL>
<LI><B>CL_DB_STDOPT</B>
<BR>
This is an alias for a recommended set of scan options.
</LI>
<LI><B>CL_DB_PHISHING</B>
<BR>
Load phishing signatures.
</LI>
<LI><B>CL_DB_PHISHING_URLS</B>
<BR>
Initialize the phishing detection module and load .wdb and .pdb files.
</LI>
<LI><B>CL_DB_PUA</B>
<BR>
Load signatures for Potentially Unwanted Applications.
</LI>
<LI><B>CL_DB_OFFICIAL_ONLY</B>
<BR>
Only load official signatures from digitally signed databases.
</LI>
<LI><B>CL_DB_BYTECODE</B>
<BR>
Load bytecode.
</LI>
</UL>
<code>cl_load()</code> returns <code>CL_SUCCESS</code> on success and another code on
failure.
<PRE>
...
struct cl_engine *engine;
unsigned int sigs = 0;
int ret;
if((ret = cl_init()) != CL_SUCCESS) {
printf("cl_init() error: %s\n", cl_strerror(ret));
return 1;
}
if(!(engine = cl_engine_new())) {
printf("Can't create new engine\n");
return 1;
}
ret = cl_load(cl_retdbdir(), engine, &sigs, CL_DB_STDOPT);
