Thanx for your reply ( and al the cool software).
Anyway, what i'm trying todo is the following. The aim is to get some 
info from the /proc filesystem to mono land. I gues i could open just a 
file handle but i wan't to to see how to expand the mono framework. So 
i've made some c-code that gets some cpu-info from /proc end passes it 
to mono land in the form of a monostring using an internall call.
Now the code works fine when i start the mono runtime from the c-code 
and use add_internal_call()  and than mono_jit_exec( ) etc.
What i would like to know is is there a way of using the internal call 
without starting the mono runtime from c-code.
e.g. mono myassembly.exe and myassembly uses a internall call in the c-code.
Or is p/invoke the only way? can use p/invoke to register a 
internal-call and than use it?
The code i wan't to make is more a proof of concept than highly usable 
but what i have in mind  in the future  is controlling  some piece of 
hardware maybe a (soft/hard)realtime process in c-code that can be 
interfaceded by mono.
