The RTM_IPV4_GET_ADDR_AND_MASK macro converts to a generic RTM_NET_ADDRESS structure and length to an IPv4 address and mask.

Syntax

void RTM_IPV4_GET_ADDR_AND_MASK(
   Addr,
   Mask,
   NetAddress
);

Parameters

Addr

Receives the converted IPv4 address.

Mask

Receives the converted IPv4 mask.

NetAddress

Specifies the network address to convert.

Return value

None

Remarks

For example, if a client supplies the NetAddress 10.10.10.24, the Addr 10.10.10.0 and the Mask 255.255.255.255 are returned.

The macro is defined as follows:

#include <windows.h>

#define RTM_IPV4_GET_ADDR_AND_MASK(Addr, Mask, NetAddress)  \
        (Addr) = (* (ULONG *) ((NetAddress)->AddrBits));    \
        (Mask) = RTM_IPV4_MASK_FROM_LEN((NetAddress)-       \
            >NumBits);
