Redirecting IO

["Peter Sommerfeld" <peter.sommerfeld@...>]

Hello everyone !

I'm new at Lua. So far I've compiled Lua 4.1a as 
Shared Lib (dll) on W2k and initalized. To interface
Lua with the GUI Lua-IO has to be redirected. The
code below works so far. An Alert Box pops up
with the Test Message but is immediatly followed by 
another one: "unable to recover; exiting" obviously 
comming from luaD_breakrun(). What's wrong here ?

Well, I didn't dig very deep into the docs  up to
now so please excuse if I've missed something
obvious.

regards

Peter

 /* open lua libs */

 lua_baselibopen (lua);
 lua_iolibopen(lua);

 /* redirect  io handler */

 lua_register(lua,"_ALERT",luaErrorHandler);

 lua_register(lua,"_INPUT",luaInputHandler);

/* test */

lua_error("TEST ERROR");
