Function Documentation

struct bio_source* rx_bio_source (  rxdrv_t *  rx  )

Returns: the I/O source from the bottom of the stack (link layer).

rxdrv_t* rx_bottom (  rxdrv_t *  rx  )

Returns: the driver at the bottom of the stack.

void rx_collect (  void   )

Collect freed stacks.

void rx_disable (  rxdrv_t *  rx  )

Disable reception, recursively. It must be called on the top layer only.

void rx_enable (  rxdrv_t *  rx  )

Enable reception, recursively. It must be called on the top layer only.

void rx_free (  rxdrv_t *  rx  )

Dispose of the driver resources, recursively and asynchronously. It must be called on the top layer only.

rxdrv_t* rx_make (  gpointer  owner, gnet_host_t *  host, const struct rxdrv_ops *  ops, gpointer  args )

rxdrv_t* rx_make_above (  rxdrv_t *  lrx, const struct rxdrv_ops *  ops, gconstpointer  args )

Creation routine for a driver to be stacked above specified lower `lrx'. Returns: NULL if there is an initialization problem.

struct bio_source* rx_no_source (  rxdrv_t *  rx  )

No I/O source can be fetched from this layer.

void rx_recv (  rxdrv_t *  rx, pmsg_t *  mb )

Inject data into driver, from lower layer.

void rx_set_data_ind (  rxdrv_t *  rx, rx_data_t  data_ind )

Set the `data_ind' callback, invoked when a new message has been fully received by the RX stack. The first argument of the routine is the layer from which data come, which will be the topmost driver when calling the external routine.
