Abstract:
|
|
|
|
CClientOxid objects represent OXIDs which are in use by one or more clients
|
|
on this machine. These are referenced by
|
|
is pinging the server of the OXID. These objects maybe kept around
|
|
after the last client reference to improve performance.

Class Description:
|
|
|
|
Represtents an OXID on some machine.
|

Members:
|
|
|
|
_plist - Embedded CPList element used to store CClientOxids
|
|
in gpOxidPList.
|
|
|
|
_oxidInfo - Static information about this OXID and its
|
|
string + security bindings.
|
|
|
|
_pMid - Pointer to the machine ID for this OXID, we
|
|
own a reference.
|
|
|
|
_fLocal - non-Zero if this OXID is on this machine. Need only 1 bit.
|
|
|
|
_fApartment - non-Zero if this process is prefers apartment model.
|
|
Meaning less for non-local OXIDs. Need only 1 bit.
