Engine structure

When all required databases are loaded you should prepare the detection engine by calling cl_engine_compile(). In case of failure you should still free the memory allocated to the engine with cl_engine_free():
	int cl_engine_compile(struct cl_engine *engine);
In our example:
	if((ret = cl_engine_compile(engine)) != CL_SUCCESS) {
	    printf("cl_engine_compile() error: %s\n", cl_strerror(ret));
	    return 1;
