Database loading

The following set of functions provides an interface for loading the virus database:

	const char *cl_retdbdir(void);

	int cl_load(const char *path, struct cl_engine **engine,
		    unsigned int *signo, unsigned int options);

cl_retdbdir returns the default (hardcoded) path to the directory with ClamAV databases. cl_load loads a single database file or all databases from a directory (if path points to a directory). The second argument is used for passing in the engine structure which should be previously initialized with NULL. A number of loaded signatures will be added to signo ⁷. The last argument can pass the following flags:

• CL_DB_STDOPT
  This is an alias for a recommended set of scan options.
• CL_DB_NCORE
  Initialize NodalCore and load the hardware database (if applicable).
• CL_DB_PHISHING
  Load phishing signatures.
• CL_DB_PHISHING_URLS
  Initialize the phishing detection module and load .wdb and .pdb files.

cl_load returns 0 (CL_SUCCESS) on success and a non-negative value on failure.

	    ...
	    struct cl_engine *engine = NULL;
	    unsigned int sigs = 0;
	    int ret;

	ret = cl_load(cl_retdbdir(), &engine, &sigs, CL_DB_STDOPT);
