41 * memory required, etc). Only called once during system startup
45 * Reset the module into it's initial system boot state. Will be called
46 * once after init(), as well as whenever the user requests a reset.

60 * Set the module into a stopped state (may be NULL)
64 * Save the module state to the FILE stream. May be NULL, in which case
65 * the module is considered to have no state.
69 * Load the saved module state from the FILE stream. May be NULL, in which
70 * case reset() will be called instead.
71 * @return 0 on success, nonzero on failure.
