catching Lua output

[Philipp Kraus <philipp.kraus@...>]

Hello,

how can I catch Lua print statements within my C code? 
My Lua scripts run within a simulation on a different host and if the scripts runs a print statement I would like to catch the output and store it in a C variable for send the output back to the client.
I run a lua_call on the C code for running the Lua function.

Thanks

Phil
