1/6/2010

This macro sets a caller-supplied variable to a Boolean value indicating whether a given Token Ring address is a broadcast address.

Syntax

VOID TR_IS_BROADCAST(
  PUCHAR _Address,
  PBOOLEAN _Result
);

Parameters

• _Address
  Points to the network address to be checked.

• _Result
  Points to a caller-supplied variable in which this macro returns TRUE if the address is broadcast.

Return Value

None.

Remarks

A broadcast address applies to all stations in the extended network.

The TR_IS_BROADCAST macro is defined as follows.

#define TR_IS_BROADCAST(_Address, _Result)                                      \
{                                                                               \
    *(_Result) = (BOOLEAN)(((*(UNALIGNED USHORT *)&(_Address)[0] == 0xFFFF) ||  \
                            (*(UNALIGNED USHORT *)&(_Address)[0] == 0x00C0)) && \
                            (*(UNALIGNED ULONG  *)&(_Address)[2] == 0xFFFFFFFF));\
}
