IPX_NETNUM_DATA structure

The IPX_NETNUM_DATA structure provides information about a specified IPX network number. Used in conjunction with getsockopt function calls that specify IPX_GETNETINFO in the optname parameter.

Syntax


typedef struct _IPX_NETNUM_DATA {
  UCHAR  netnum[4];
  USHORT hopcount;
  USHORT netdelay;
  INT    cardnum;
  UCHAR  router[6];
} IPX_NETNUM_DATA, *PIPX_NETNUM_DATA;

Members

netnum

IPX network number for which information is being requested.

hopcount

Number of hops to the IPX network being queried, in machine order.

netdelay

Network delay tick count required to reach the IPX network, in machine order.

cardnum

Adapter number used to reach the IPX network. The adapter number is zero based, such that if eight adapters are on a given computer, they are numbered 0-7.

router

Media Access Control (MAC) address of the next-hop router in the path between the computer and the IPX network. This value is zero if the computer is directly attached to the IPX network.

Remarks

If information about the IPX network is in the computer's IPX cache, the call will return immediately. If not, RIP requests are used to resolve the information.
