Re: Simple lua code crashing...

[Austin Einter <austin.einter@...>]

I changed the order , that is first pushing string, next pushing length.

Same crash observed.

No,

this gives the reverse order.

I am bit new, but I hope push order is fine. First I push length, next msg.

And in function, my 1st arg is msg, next arg is length.

Is not this order right?

I haven't run your code, but I can see that you're pushing arguments in the wrong order.

Otherwise, you should use pushlstring (with your length) instead of pushstring;

Also, passing the length as a parameter itself is pointless: use the length operator '#'
