Data Structures
struct	mq_udp_info
	The "meta data" attached to each message block enqueued yields routing information, perused by the queue to route messages. More...
struct	mq_udp_info_extended
	The extended meta data are used when the enqueued message is already extended. More...
Functions
	RCSID ("$Id:mq_udp.c, v 1.18 2005/09/10 08:17:28 daichik Exp $")
void	mq_udp_service (gpointer data)
	Service routine for UDP message queue.
void	mq_udp_pmsg_free (pmsg_t *mb, gpointer arg)
	Free routine for plain metadata.
void	mq_udp_pmsg_free_extended (pmsg_t *mb, gpointer arg)
	Free routine for extended metadata, invoking the original free routine on the original metadata.
pmsg_t *	mq_udp_attach_metadata (pmsg_t *mb, gnet_host_t *to)
	Attach meta information to supplied message block, returning a possibly new message block to use.
mqueue_t *	mq_udp_make (gint maxsize, struct gnutella_node *n, struct txdriver *nd)
	Create new message queue capable of holding `maxsize' bytes, and owned by the supplied node.
void	mq_udp_putq (mqueue_t *q, pmsg_t *mb, gnet_host_t *to)
	Enqueue message, which becomes owned by the queue.
void	mq_udp_node_putq (mqueue_t *q, pmsg_t *mb, gnutella_node_t *n)
	Enqueue message to be sent to the ip:port held in the supplied node.
void	mq_no_putq (mqueue_t *unused_q, pmsg_t *unused_mb)
	Disable plain mq_putq() operation on an UDP queue.
Variables

Function Documentation

void mq_no_putq (  mqueue_t *  unused_q, pmsg_t *  unused_mb )  [static]

Disable plain mq_putq() operation on an UDP queue.

pmsg_t* mq_udp_attach_metadata (  pmsg_t *  mb, gnet_host_t *  to )  [static]

Attach meta information to supplied message block, returning a possibly new message block to use.

mqueue_t* mq_udp_make (  gint  maxsize, struct gnutella_node *  n, struct txdriver *  nd )

Create new message queue capable of holding `maxsize' bytes, and owned by the supplied node.

void mq_udp_node_putq (  mqueue_t *  q, pmsg_t *  mb, gnutella_node_t *  n )

Enqueue message to be sent to the ip:port held in the supplied node.

void mq_udp_pmsg_free (  pmsg_t *  mb, gpointer  arg )  [static]

Free routine for plain metadata.

void mq_udp_pmsg_free_extended (  pmsg_t *  mb, gpointer  arg )  [static]

Free routine for extended metadata, invoking the original free routine on the original metadata.

void mq_udp_putq (  mqueue_t *  q, pmsg_t *  mb, gnet_host_t *  to )

Enqueue message, which becomes owned by the queue. The data held in `to' is copied, so the structure can be reclaimed immediately by the caller.

void mq_udp_service (  gpointer  data  )  [static]

Service routine for UDP message queue.

RCSID (  "$Id:mq_udp.  c, v 1.18 2005/09/10 08:17:28 daichik Exp $"  )
