This file contains the class declarations for the SERVICE_ENUM
|
||
|
|
enumerator class and its associated iterator class.
|
||
|
|
|
||
|
|
The SERVICE_ENUM class is used to enumerate the services installed
|
||
|
|
on a target (possibly remote) server.
|
||
|
|
|
||
|
|
NOTE: This class uses the Win32 Service Control API.

SYNOPSIS: This is basically the return type from the
|

|
|
SERVICE_ENUM_ITER iterator.
|
||
|
|
|
||
|
|
INTERFACE: QueryServiceName - Returns the name of the service.

||
|
|
QueryCurrentState - Returns the current state of
|
||
|
|
the service (SERVICE_*).
|
||
|
|
|
||
|
|
QueryControlsAccepted - Bitmask indicating which operations
|
||
|
|
(stop,pause,continue) may be
|
||
|
|
performed (SERVICE_ACCEPT_*).
|

|
|

PARENT: ENUM_OBJ_BASE

||
|
|
|
||
|
|
NOTE: The QueryCurrentState & QueryControlsAccepted accessor
|
||
|
|
return WIN32-style values, *not* LM-style values!
