OpenVPN - source code, can't find "msg" function declaration

Torxed

I've been coaming the source code for a few hours now.
If ended up writing a short python script to do the job for me at the end to really make sure i didn't miss it.

But i can't find it..
At first i assumed:

void
msg ( ... )
{
    ...
}

Because that's the syntax OpenVPN mostly consists of, but i've tried all possible combinations and gone through the entire source code and i just.. can't.. find it..

Where is "msg" defined?
It's used _everywhere_ for all the output/logging so it has to be somewhere..

For instance, error.c:

  if (flags & M_FATAL)
    msg (M_INFO, "Exiting");

Reason being that i'm adding in windows event-log support for OpenVPN.
I've got the C++ linkage working when building openvpn and i've successfully managed to get the logging-to-windows-eventlog to work.. I just need to find the centralized function for all the output/log-messages.. that is msg() >_<

* Using the OpenVPN 2.2.2 sourcecode

msg() is a macro found in error.h

Almost guessed so, pre-processes into "x_msg"?

yup, but remember to add "#ifdef WIN32" blocks for Windows.
