Re: How do I change Environment variables

[Robert Raschke <rrlua@...>]

For what it's worth, here's how I do putenv() on Windows:

int
lputenv(lua_State *L)
{
	int n = lua_gettop(L);    /* number of arguments */
	if (n != 1) {
		lua_pushstring(L, "wrong number of arguments to function `putenv'");
		lua_error(L);
	} else {
		if (_putenv(lua_tostring(L, 1)) != 0) {
			lua_pushstring(L, "calling function `putenv' failed");
			lua_error(L);
		}
	}
	return 0;
}

And then add

	lua_register(L, "putenv", lputenv);

after creating your Lua state and before invoking your Lua program.
And use it like

	putenv "env_var=value"
