Return value of attached command

[jounathaen]

Hi,

I looks to me, as if the return value of the process which reptyr attaches to cannot be retrieved.
Is there some technical limitation, is it not implemented or am I not using it correctly?

It is not currently implemented, and would be somewhat challenging to implement and would require some tradeoffs -- you would have to stay attached with ptrace in order to wait on the child and capture the exit status, which had some ongoing behavior implications. I doubt I'm likely to get to this soon if ever.
