So *you* are writing that P/Invoke declaration? If so, that's the
problem -- no Unix platform provides ADVAPI32.DLL, hence the
Mono provides a runtime environment for executing .NET code, it does NOT
duplicate all of Win32 to permit portability of any random piece of .NET
code to non-Windows platforms. (That's what the Wine project is for --
pity Mono doesn't currently execute under Wine....)
The fix to your problem is to not use ADVAPI32.DLL under non-Windows
platforms, and use an alternate. Or better, use
System.Diagnostics.EventLog to deal with the event log instead of using
OpenEventLog() directly. The downside is that under Linux the EventLog
class doesn't read dmesg(1) messages, but only messages created by other
Mono EventLog instances.
