Re: [ros-dev] EventLog

[Saveliy Tretiakov]

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.
