Look at how liolib.c (in Lua source) handles passing file pointers to
and from Lua. You will see that Lua uses a full userdata to hold these
pointers. Assuming the io library is included in your application, you
can add a new file from C using something like:
#include "lualib.h"
...
*(lua_newuserdata(L, sizeof(FILE *))) = fp;
luaL_getmetatable(L, LUA_FILEHANDLE);
lua_setmetable(L, -2);
/* you now have a Lua FILE object on the stack */
