Function Documentation

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

Invoked when the output file descriptor can accept more data.

RCSID (  "$Id:tx_dgram.  c, v 1.21 2005/08/31 21:37:28 rmanfredi Exp $"  )

struct bio_source* tx_dgram_bio_source (  txdrv_t *  tx  )  [static]

Returns: the I/O source of this level.

void tx_dgram_destroy (  txdrv_t *  tx  )  [static]

Get rid of the driver's private data.

void tx_dgram_disable (  txdrv_t *  tx  )  [static]

Disable servicing of upper TX queue.

void tx_dgram_enable (  txdrv_t *  tx  )  [static]

Allow servicing of upper TX queue when output fd is ready.

void tx_dgram_flush (  txdrv_t *  unused_tx  )  [static]

Nothing to do.

const struct txdrv_ops* tx_dgram_get_ops (  void   )

gpointer tx_dgram_init (  txdrv_t *  tx, gpointer  args )  [static]

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

size_t tx_dgram_pending (  txdrv_t *  unused_tx  )  [static]

No data buffered at this level: always returns 0.

ssize_t tx_dgram_sendto (  txdrv_t *  tx, gnet_host_t *  to, gpointer  data, size_t  len )  [static]

Send buffer datagram to specified destination `to'. Returns: amount of bytes written, or -1 on error with errno set.

void tx_dgram_shutdown (  txdrv_t *  unused_tx  )  [static]

Nothing to do.

gint tx_dgram_write_error (  txdrv_t *  tx, gnet_host_t *  to, const char *  func )  [inline, static]
