LCP
[PPP]

Collaboration diagram for LCP:

Detailed Description

Link control protocol.


Functions

void LcpRxProtRej (NUTDEVICE *dev)
void NutLcpInput (NUTDEVICE *dev, NETBUF *nb)
 Handle incoming LCP packets.
int NutLcpOutput (NUTDEVICE *dev, u_char code, u_char id, NETBUF *nb)
 Send a LCP packet.
void LcpResetOptions (NUTDEVICE *dev)
void LcpTxConfReq (NUTDEVICE *dev, u_char id, u_char rejected)
void LcpTxProtRej (NUTDEVICE *dev, u_short protocol, NETBUF *nb)

Variables

u_long new_magic
u_long new_magic

Function Documentation

void NutLcpInput (  NUTDEVICE *  dev,
NETBUF *  nb
) 
 

Handle incoming LCP packets.

Packets not destined to us or packets with unsupported address type or item length are silently discarded.

Note:
This routine is called by the Ethernet layer on incoming ARP packets. Applications typically do not call this function.
Parameters:
dev Identifies the device that received the packet.
nb Pointer to a network buffer structure containing the ARP packet.

int NutLcpOutput (  NUTDEVICE *  dev,
u_char  code,
u_char  id,
NETBUF *  nb
) 
 

Send a LCP packet.

Note:
Applications typically do not call this function.
Parameters:
dev Identifies the device to use.
nb Network buffer structure containing the packet to send or null if the packet contains no information. The structure must have been allocated by a previous call NutNetBufAlloc() and will be freed when this function returns.
Returns:
0 on success, -1 in case of any errors.
