The source Tony, use the source.

Now, seriously. Every luaL_* function is done in term of the
primitives in lua_*. If you look at lauxlib.h you'll find
luaL_do{string,file} are just luaL_loadXX plus lua_pcall. In turn all
luaL_load* end up in luaL_loadbufferx, which just uses lua_load (
that's the primitive one ) which is documented as reading either text
or binary. So binary is fine in load_buffer. As you probably do not
want to mingle with writing a reader function ( as lualib has a
perfectly fine one which it uses to implement the loadbuffers ) you
just need to copy a bit fom luaL_dostring and make yourself a
luaL_dobuffer[x] using loadBufferX and lua_pcall in the same way
luaL_dostring is done. Easy peasy, faster to do than tell.
