Access userdata content in Corona SDK

From an in-app server, I receive a table and inside this table there's a key marked as userdata. I red this type is there to allow arbitrary C data to be stored inside Lua variables. Is it possible to read/access its content from Lua?

Lua can't read data from userdata, unless you write native functions that will read and return bytes from userdata in some way you will find convenient - as array of numbers, as string, or maybe just returning single byte at specified index.
Maybe your host app/framework already has these functions, but Lua itself definitely can't do that.
Corona SDK's page for userdata only quotes Lua's doc, telling basically the same - there's no operations on userdata in Lua, except assignment and identity test.
