Re: Dump all strings/symbols?

["Research" <research@...>]

After messing about with this for a while, I found the following adapted 
from the manual. If I call this function after nil'ing and gc'ing and 
they're gone, is there anywhere else in Lua I need to check to be sure 
they're really gone?

Thanks

// function void ScriptDumpGlobals(lua_State *luaStatePtr)
void ScriptDumpGlobals(lua_State *luaStatePtr)
{
int t;
printf("Lua globals table dump start:\n");
// table is in the stack at index `t'
t = LUA_GLOBALSINDEX;
lua_pushnil(luaStatePtr); // first key
while(lua_next(luaStatePtr, t) != 0)
{
// `key' is at index -2 and `value' at index -1
switch(lua_type(luaStatePtr, -2))
{
case LUA_TSTRING:
printf("%s\n", lua_tostring(luaStatePtr, -2));
break;
default:
printf("%s - %s\n", lua_typename(luaStatePtr, lua_type(luaStatePtr, -2)), 
lua_typename(luaStatePtr, lua_type(luaStatePtr, -1)));
break;
}
lua_pop(luaStatePtr, 1); // removes `value'; keeps `key' for next iteration
}
printf("Lua globals table dump end.\n\n");
}
