MIB_BOUNDARYROW structure (iprtrmib.h)

  • Article

The MIB_BOUNDARYROW structure contains the IPv4 group address value and mask for a multicast boundary.

Syntax

typedef struct {
  DWORD dwGroupAddress;
  DWORD dwGroupMask;
} MIB_BOUNDARYROW, *PMIB_BOUNDARYROW;

Members

dwGroupAddress

The 32-bit integer representation of the IPv4 group address which, when combined with the corresponding value in dwGroupMask, identifies the group range for which the scoped boundary exists.

Note  Scoped addresses must come from the range 239.*.*.* as specified in RFC 2365.
 

dwGroupMask

The 32-bit integer representation of the IPv4 group address mask which, when combined with the corresponding value in dwGroupAddress, identifies the group range for which the scoped boundary exists.

Remarks

Note that the Iprtrmib.h header file is automatically included in the Iphlpapi.h header file. The Iprtrmib.h header file should never be used directly.
