Re: [bug-gawk] Problem with printing 5000 lines to a coprocess

[Aharon Robbins]

Hi. Sorry I haven't been able to be involved in the discussion.

If I understand how things work, using ptys solves the problem because
the tty driver always returns data to the read system call after one line
has been seen (the newline character). So the program at the other end
can try to read as much as it wants, but it only gets one line at a time.

The main caveat is that the pty won't pass all binary data; some control
characters have an influence on how it behaves (such as ^D for EOF).

I will try to add something to manual, but am not sure when I'll get to it.

Thanks,

Arnold
