I'm aware of that it's not the best way. 
According to the documentation at
http://winehq.org/site/docs/wineusr-guide/using-regedit
there are two ways to access the registry - using file access and using
regedit.

AFAIK what You mention these are C API calls. I'm trying to access 
the registry from PERL. If registry access should be done only via 
API calls, then there is Regedit tool which uses the API calls. 
That leads to the second point, enhancing regedit.

Believe it or not, there are UNIXes without /dev/stderr and /dev/stdout.
Having regedit option to flush its output to STDOUT (and to get its
input from STDIN) would be very helpful - and in case of STDOUT output
very easy to implement.
