Re: How can I do sethook() to all coroutines of a Lua state?

[Oliver Kroth <oliver.kroth@...>]

Thijs,

thank you for your valuable information. I managed now to kill the main 
thread by hooking into G(L)->mainthread, and the current thread (if 
different) a function that inserts itself again, and errors:

void fullstop( lua_State *L, lua_Debug *ar )
{
    (void)ar;  /* unused arg. */
    lua_sethook( L, fullstop, LUA_MASKCALL | LUA_MASKRET | 
LUA_MASKCOUNT, 1 );
    luaL_error( L, "stopped");
}

...

lua_sethook( mainthread, fullstop, LUA_MASKCALL | LUA_MASKRET | 
LUA_MASKCOUNT, 1 );
if (mainthread != L)
    lua_sethook( L, fullstop, LUA_MASKCALL | LUA_MASKRET | 
LUA_MASKCOUNT, 1 );
