### Limits

When you create a new engine with `cl_engine_new()`, it will have all internal settings set to default values as recommended by the ClamAV authors. It's possible to check and modify the values (numerical and strings) using the following set of functions:

    int cl_engine_set_num(struct cl_engine *engine,
      enum cl_engine_field field, long long num);

    long long cl_engine_get_num(const struct cl_engine *engine,
      enum cl_engine_field field, int *err);

    int cl_engine_set_str(struct cl_engine *engine,
      enum cl_engine_field field, const char *str);

    const char *cl_engine_get_str(const struct cl_engine *engine,
      enum cl_engine_field field, int *err);

Please don't modify the default values unless you know what you're doing. Refer to the ClamAV sources (clamscan, clamd) for examples.
