Abstract:
|
|
|
|
Process objects represent local clients and servers. These
|
|
objects live as context handles.
|
|
|
|
There are relativly few of these objects in the universe.

Class Description:
|
|
|
|
An instance of this class is created for each process
|
|
using the OR as either a client or server.
|
|
|
|
The process object is referenced by server OXIDs and has
|
|
one implicit reference by the actual process (which is
|
|
dereferenced during the context rundown). Instances of
|
|
these objects are managed by the RPC runtime as context
|
|
handles.
|
|
|
|
Members:
|
|
|
|
_pToken - A pointer to the CToken instance of the process.
|
|
|
|
_csCallbackLock - use to serialize callback to LazyUseProtseq
|
|
|
|
_hProcess - An RPC binding handle back to the process.
|
|
|
|
_pdsaLocalBindings - The string bindings of the process, including
|
|
local only protseqs
|
|
|
|
_pdsaRemoteBindings - A subset of _pdsaLocalBindings not containing
|
|
any local-only protseqs
|
|
|
|
_blistOxids - A CBList containing pointers to the CServerOxid's
|
|
owned by this process, if any.
|
|
|
|
_blistOids - A CBList of pointers to CClientOid's which this
|
|
process is using and referencing, if any.
|
|
|
|
_listClasses - A CBList of registration handles for classes that
|
|
a server process has registered.
|
|
|
|
_fReadCustomProtseqs - a flag to indicate if the server has been queried
|
|
for custom protseq and endpoints (specific to the server)
|
|
|
|
_pcpaCustomProtseqs - a pointer to a counted array of custom protseqs
|
|
|
|
_dwFlags -- state bits for this process
|
|
|
|
_pSCMProcessInfo -- pointer to the current SCMProcessInfo struct for ourself
|
|
|
|
_ftCreated - the filetime that this object was created.
