Abstract:
|
|
|
|

|
|
unique ID for that machine.

Class Description:
|
|
|
|
Represents the local and remote machines. Each unique (different)
|
|
set of string bindings and security bindings are assigned a unique
|
|
local ID. This ID is used along with the OID and OXID of the remote
|
|
machine objects index these objects locally. Instances of this class
|
|
are referenced by CClientSets which are referenced by CClientOids.
|
|
This class is indexed by string and security bindings. There is no
|
|
index by MID.
|
|
|
|
Members:
|
|
|
|
_id - The locally unique ID of this set of bindings.
|
|
|
|
_iStringBinding - Index into _dsa->aStringArray of the
|
|
compressed string binding used to create _hMachine.
|
|
|
|
_fLocal - TRUE if these are bindings for the local machine.
|
|
|
|
_fStale - TRUE if this mid represents out-of-date bindings for
|
|
the local machine.
|
|
|
|
_fSecure - TRUE if not local and both machines share an authentication
|
|
service.
|
|
|
|
_fDynamic - TRUE if we believe the remote machine's OR
|
|
is not running in the endpoint mapper process.
|
|
|
|
_dsa - The set of compressed bindings.
|
|
|
|
_wAuthnSvc -- the authentication service used to talk to the machine
|
|
that this CMid represents
