• _Address
  Points to a network address.

• _Result

A source routing address has the source-routing bit asserted.

The TR_IS_SOURCE_ROUTING macro is defined as follows.

#define TR_IS_SOURCE_ROUTING(_Address, _Result)                          \
{                                                                        \
    *(_Result) = (BOOLEAN)((_Address)[0] & 0x80);                        \
}
