RE: [ros-dev] EventLog

[Rick Langschultz]

I think without a service host process I think implementing a service may be
a little to early. Sure you can test the file on Windows 2000 or XP but they
may have some sort of effect on the binary itself, but how will ReactOs
react to the binary? I am sure the service will not start.

Ok, I decided to leave EventLog and do something else until required 
widl features will be implemented :)
Are there any undocumented rpc interfaces needed for compatibility with 
windows? If yes, I can try to reverse engeneer them.
I've just compared our svcctl.idl to IDA disassembly of advapi32. GUID 
and stub order are the same(someone already researched it?). Missing 
stubs are:
10 - I_ScSetServiceBitsW
11 - ChangeServiceConfigW
13 - EnumDependentServicesW
14 - EnumServiceGroupW
17 - QueryServiceConfigW
18 - QueryServiceLockStatusW
19 - StartServiceW
20 - GetServiceDisplayNameW
21 - GetServiceKeyNameW
22 - I_ScSetServiceBitsA
23 - ChangeServiceConfigA
24 - CreateServiceA
25 - EnumDependentServicesA
26 - EnumServicesStatusA
29 - QueryServiceConfigA
30 - QueryServiceLockStatusA
31 - StartServiceA
32 - GetServiceDisplayNameA
33 - GetServiceKeyNameA
34 - Unknown
35 - EnumServiceGroupW
36 - ChangeServiceConfig2A
37 - ChangeServiceConfig2W
38 - QueryServiceConfig2A
39 - QueryServiceConfig2W
40 - QueryServiceStatusEx
41 - EnumServicesStatusExA
42 - EnumServicesStatusExW
43 - I_ScSendTSMessage

I didn't looked at parameters yet.
