  • Article

The FWP_V6_ADDR_AND_MASK structure specifies an IPv6 address and mask.

Syntax

typedef struct FWP_V6_ADDR_AND_MASK_ {
  UINT8 addr[16];
  UINT8 prefixLength;
} FWP_V6_ADDR_AND_MASK;

Members

addr[16]

An array of size FWP_V6_ADDR_SIZE bytes containing an IPv6 address. FWP_V6_ADDR_SIZE maps to 16.
