The SendARP function sends an ARP request to obtain the physical address that corresponds to the specified destination IP address.
DWORD SendARP( IPAddr DestIP,// destination IP address IPAddr SrcIP, // IP address of sender PULONG pMacAddr, // returned physical address PULONG PhyAddrLen // length of returned physical addr.);
Specifies the destination IP address. The ARP request attempts to obtain the physical address that corresponds to this IP address.
Specifies the IP address of the sender. This parameter is optional. The caller may specify zero for the parameter.
Pointer to a ULONG variable. On successful return, this variable contains the physical address that corresponds to the IP address specified by the DestIP parameter.
Pointer to a ULONG variable. On successful return, this variable contains the length of the physical address pointed to by the pMacAddr parameter.
If the function succeeds, the return value is NO_ERROR.
If the function fails, use FormatMessage to obtain the message string for the returned error.
