  • Maximum for gets

    Is there a limit to the number of characters that gets can read at a time?

    in principle, it is limited only by the max length of Tcl string (~2GB
    in Tcl 8.6), that's why when using it with sockets, it is recommended to combine gets with [chan pending] to protect against malicious or
    misbehaving peer, see https://wiki.tcl-lang.org/page/chan+pending

    Thank you for the tip. This is for a local script sending another some
    data via std channels. I was afraid that they might have a problem with
    data sizes around 5K :-)
