I'm writing (yet another) C++ wrapper for Lua
(5.0b) and I'm having serious problems with a function that should be very
very simple :) Here's my code to get a global string:
*****************************************
std::string Cscript::GetString(char
*varName)
{
std::string str;
lua_pushstring(lua,
varName);
lua_gettable(lua, LUA_GLOBALSINDEX);
str =
lua_tostring(lua,lua_gettop(lua));
lua_pop(lua,1);
return str;
}
*********************************
It works like expected the first time, but then
the second time I call it it crashes on the lua_pushstring line. What am
I doing wrong?
