Detailed Description

information about peers in a DTLS session

Definition in file peer.h.

Typedef Documentation

typedef struct dtls_peer_t dtls_peer_t

Holds security parameters, local state and the transport address for each peer.

Enumeration Type Documentation

enum dtls_peer_type

Enumerator
DTLS_CLIENT
DTLS_SERVER

Definition at line 47 of file peer.h.

Function Documentation

void dtls_free_peer

(

dtls_peer_t *

peer

)

Releases the storage allocated to peer.

Definition at line 41 of file peer.c.

dtls_peer_t* dtls_new_peer

(

const session_t *

session

)

Creates a new peer for given session. The current configuration is initialized with the cipher suite TLS_NULL_WITH_NULL_NULL (i.e. no security at all). This function returns a pointer to the new peer or NULL on error. The caller is responsible for releasing the storage allocated for this peer using dtls_free_peer().

Parameters

session

The remote peer's address and local interface index.

Returns

A pointer to a newly created and initialized peer object or NULL on error.

Definition at line 72 of file peer.c.

static int dtls_peer_is_connected ( const dtls_peer_t *  peer )

inlinestatic

Checks if given peer is connected. This function returns 1 if connected, or 0 otherwise.

Definition at line 144 of file peer.h.

static dtls_state_t dtls_peer_state ( const dtls_peer_t *  peer )

inlinestatic

Returns the current state of peer.
