#define ETH_ALEN 6 //Octets in one ethernet addr
typedef unsigned char u_int8_t;
#pragma pack(1)
typedef struct ether_addr {
u_int8_t ether_addr_octet[ETH_ALEN];
} ETHER_ADDR, *PETHER_ADDR;
..so, if your binary is arpmac, then
PETHER_ADDRC pMac;
pMac = (PETHER_ADDR) &arpmac;
Then you can easily feed the individual octets to sprintf via
pMac->ether_addr_octet[0], pMac->ether_addr_octet[1], etc., to end up
with a well formed hex string for display.
Sorry. It's not my place to tell you how to do things. iPeng is a
wonderful piece of software and my life is definitely enriched by using
it. Thanks.
