- Subject: When will userdate be freed/gced?
- From: Marc Balmer <marc@...>

In a C function that is called from Lua, I use the following idiom:
char *s;
...
s = lua_newuserdata(L, 128);
...
return;
After this function returns, what happens to the userdata? Will it be garbage collected eventually or do I have to free() the pointer returned by lua_newuserdata()? How does Lua "know" when the userdata is no longer used?
