Detailed Description

Function Documentation

void broadcast_close

(

struct broadcast_conn *

c

)

Close a broadcast connection.

Parameters

c	A pointer to a struct broadcast_conn This function closes a broadcast connection that has previously been opened with broadcast_open(). This function typically is called as an exit handler.

void broadcast_open	(	struct broadcast_conn *	c,
		uint16_t	channel,
		const struct broadcast_callbacks *	u
	)

Set up an identified best-effort broadcast connection.

Parameters

c	A pointer to a struct broadcast_conn
channel	The channel on which the connection will operate
u	A struct broadcast_callbacks with function pointers to functions that will be called when a packet has been received This function sets up a broadcast connection on the specified channel. The caller must have allocated the memory for the struct broadcast_conn, usually by declaring it as a static variable. The struct broadcast_callbacks pointer must point to a structure containing a pointer to a function that will be called when a packet arrives on the channel.

int broadcast_send

(

struct broadcast_conn *

c

)

Send an identified best-effort broadcast packet.

Parameters

c	The broadcast connection on which the packet should be sent

Return values

Non-zero

if the packet could be sent, zero otherwise This function sends an identified best-effort broadcast packet. The packet must be present in the packetbuf before this function is called. The parameter c must point to a broadcast connection that must have previously been set up with broadcast_open().
