Function Documentation

void ARPInit (  void   )

ARP Cache is initialized.

BOOL ARPIsResolved (  IP_ADDR *  IPAddr, MAC_ADDR *  MACAddr )

This function is used to retrieve the MAC Address for a given IP address. This information will be received via ARP after sending an ARP request over the network. If we have a destination IP address, but not it's MAC address, we will send an ARP request, and wait for an ARP reply. As soon as we receive the reply, the requested MAC address can be retrieve via this function. Note: This function is available only when STACK_CLIENT_MODE is defined. Parameters: IPAddr  IPAddress to be resolved. MACAddr  Buffer to hold corresponding MAC Address. Returns: TRUE if given IP Address has been resolved. FALSE otherwise. Examples: ex_tcp_client.c, ex_udp_client.c, and ex_udp_client2.c.

BOOL ARPProcess (  void   )

Performes ARP processing. Pre-Condition: ARP packet is ready in MAC buffer. Returns: ARP FSM is executed.

void ARPResolve (  IP_ADDR *  IPAddr  )

An ARP request is sent. This function is available only when STACK_CLIENT_MODE is defined. Parameters: IPAddr  - IP Address to be resolved. For example, if IP address is "192.168.1.0", then: IPAddr.v[0] = 192 IPAddr.v[1] = 168 IPAddr.v[2] = 1 IPAddr.v[3] = 10 Examples: ex_tcp_client.c, ex_udp_client.c, and ex_udp_client2.c.
