Function Documentation

void is_readable (  gpointer  data, gint  unused_source, inputevt_cond_t  cond )  [static]

Invoked when the input file descriptor has more data available.

RCSID (  "$Id:rx_link.  c, v 1.13 2005/11/30 16:43:41 rmanfredi Exp $"  )

struct bio_source* rx_link_bio_source (  rxdrv_t *  rx  )  [static]

Returns: I/O source of the lower level.

void rx_link_destroy (  rxdrv_t *  rx  )  [static]

Get rid of the driver's private data.

void rx_link_disable (  rxdrv_t *  rx  )  [static]

Disable reception of data.

void rx_link_enable (  rxdrv_t *  rx  )  [static]

Enable reception of data.

const struct rxdrv_ops* rx_link_get_ops (  void   )

gpointer rx_link_init (  rxdrv_t *  rx, gconstpointer  args )  [static]

Initialize the driver. Always succeeds, so never returns NULL.

void rx_link_recv (  rxdrv_t *  rx, pmsg_t *  mb )  [static]

Inject data into driver. Since we normally read from the network, we don't have to process those data and can forward them directly to the upper layer.
