loadlib allowed in lua hooks?
Posted: 13.09.2007, 08:55
Recently I managed to get a Lua loadlib to work in a lua hook.
I used "require" to include an external lua script, and that lua script called package.loadlib() to load a dll on Windows 2000 SP4.
This worked just fine... but what does this say about this part of the code in celx.cpp?
Is loadlib supposed to be disallowed?
BTW, I'm using Lua 5.1 and CVS celestia sources.

Code: Select all
// Permit access to the package library, but prohibit use of the loadlib
// function.
void LuaState::allowLuaPackageAccess()
{
#if LUA_VER >= 0x050100
openLuaLibrary(state, LUA_LOADLIBNAME, luaopen_package);
// Disallow loadlib
lua_getfield(state, LUA_GLOBALSINDEX, "package");
lua_pushnil(state);
lua_setfield(state, -2, "loadlib");
lua_pop(state, 1);
#endif
