• issues with pipe/fork

    From candycane@VERT/CONCHAOS to All on Wed Aug 2 20:08:43 2023
    Hello!
    I'm having issues with pipe() and fork() making a 2 way pipe.
    The attached pastebin is somewhat far down in the function, and seemingly nothing happens when its run. The "done" puts() command isn't run either, it just returns with no error code. Any help?

    In Synchronet, the source for the pipe/fork logic is in xtrn.cpp -> sbbs_t::external() (for *nix). Take a look at that for a working example.

    You haven't really described what you're trying to (what's the *goal* of your pipe and fork?).

    I was trying to do a bi directional pipe, like

    socket -> A -> rz
    rz -> B -> socket

    where rz's standard in/out are pointed to A and B.
    However, I ended up fixing it by myself, after a bunch of research.
