Best way to save/re-load an lua state

["kathrin_69@..." <kathrin_69@...>]

Hi,

I want to save the state of a Lua VM to a file to re-load and restart 
execution later.

Three options come to my mind:

1. Serializing the global index table of the VM. I even found a library 
called "Pluto" which promises to do this.

2. Trying to make a deep copy of the lua_State* pointing to a VM and 
save/load the binary data.

3. Trying to overwrite malloc/free for the Lua.dll, place all memory the 
VM holds in an pre-allocated chunk. Save and re-load that whole chunk. 
I'm not sure If I'm yet experienced (in C/C++) enough to get this done. 
Probably not.



My Questions are:

1. Which of that options will work or which one are used and which not?
2. Are there any other options I missed?
3. Which option is most promising in terms of time and complexity?
4. Are there any other helper libraries (beside Pluto) which helps doing 
one of the options?

Thank you!

Regards
Joerg
