Returns lua_newuserdata a constant address?

Hello,

Is the pointer returned by lua_newuserdata() a constant one or exists a
possibility that the memory block will be moved by lua and the address
of the returned memory block change during garbage collection?

I plan to use a C-pointer stored outside the lua context pointing to a
memory block returned by lua_newuserdata().

I know already, if there aren't any references from lua to the userdata
object the memory block will be collected and my pointer become invalid.

Michael
