这是一段通过socket连接获取远程机器的Mac地址，第一个参数时int sockfd，我用的是TCustomSocket* Socket,请问怎么转换Socket然后作为参数传入此函数。

int getpeermac( int sockfd, char *buf )
{
int ret =0;
struct arpreq arpreq;
struct sockaddr_in dstadd_in;
socklen_t len = sizeof( struct sockaddr_in );
memset( &arpreq, 0, sizeof( struct arpreq ));
memset( &dstadd_in, 0, sizeof( struct sockaddr_in ));
if( getpeername( sockfd, (struct sockaddr*)&dstadd_in, &len ) < 0 )
err_err("getpeername()");
else
{
memcpy( &arpreq.arp_pa, &dstadd_in, sizeof( struct sockaddr_in ));
strcpy(arpreq.arp_dev, "eth1");
arpreq.arp_pa.sa_family = AF_INET;
arpreq.arp_ha.sa_family = AF_UNSPEC;
if( ioctl( sockfd, SIOCGARP, &arpreq ) < 0 )
err_err("ioctl SIOCGARP");
else
{
unsigned char* ptr = (unsigned char *)arpreq.arp_ha.sa_data;
ret = sprintf(buf, "%02x%02x%02x%02x%02x%02x", *ptr, *(ptr+1), *(ptr+2), *(ptr+3), *(ptr+4), *(ptr+5));
}
}
return ret;
}
int getpeermac( int sockfd, char *buf )
{
int ret =0;
struct arpreq arpreq;
struct sockaddr_in dstadd_in;
socklen_t len = sizeof( struct sockaddr_in );
memset( &arpreq, 0, sizeof( struct arpreq ));
memset( &dstadd_in, 0, sizeof( struct sockaddr_in ));
if( getpeername( sockfd, (struct sockaddr*)&dstadd_in, &len ) < 0 )
err_err("getpeername()");
else
{
memcpy( &arpreq.arp_pa, &dstadd_in, sizeof( struct sockaddr_in ));
strcpy(arpreq.arp_dev, "eth1");
arpreq.arp_pa.sa_family = AF_INET;
arpreq.arp_ha.sa_family = AF_UNSPEC;
if( ioctl( sockfd, SIOCGARP, &arpreq ) < 0 )
err_err("ioctl SIOCGARP");
else
{
unsigned char* ptr = (unsigned char *)arpreq.arp_ha.sa_data;
ret = sprintf(buf, "%02x%02x%02x%02x%02x%02x", *ptr, *(ptr+1), *(ptr+2), *(ptr+3), *(ptr+4), *(ptr+5));
}
}
return ret;
}
