Routine Description:

|
Arguments:
|

|
|

|
CurrentState - Indicates the current state of the service
|
||
|
Win32ExitCode - Specifies a Win32 error code that the service uses to
|
||
|
report an error that occurs when it is starting or stopping.
|
||
|
WaitHint - Specifies an estimate of the amount of time, in milliseconds,
|
||
|
that the service expects a pending start, stop, or continue
|
||
|
operation to take before the service makes its next call to the
|
||
|
SetServiceStatus function with either an incremented dwCheckPoint
|
||
|
value or a change in dwCurrentState.
|

|

Return Value:

Return code. Return zero for success, all other
