/prog/ - hooks and callbacks

Name: Anonymous 2011-01-14 10:33

Ive read definitions of both of these and I just dont have a clear idea of what they are. What I think they are is:

hook: replacing an interface function with your own function to change the functionality of an interface

callback: putting a function call inside a function call so when you call a function it calls your function that you gave it

is this right?

depends on context, eg in some VCS hooks are scripts that are ran pre/post commit.

callback is usually when you're dealing with async programming: you request for some operation that takes time to take place and supply a function that should eventually be called with the result.

What?

A hook is something you hook into.
A callback is a function that gets called back.

How do we know you are the real /prog/'s VIPPER?
There is more than one VIPPER here.
You didn't even JEWS in two posts!
There was no need for JEWS as the thread had no un-VIP elements in it.
Besides the thread was finished by >>5.

No thats not what i meant.
What i need is to connect a VT to a computer over rs232 null modem.

Then just enable terminal service on that port. It's been a while since I linux'd, but look up inittab and getty.

I am not sure what you mean, there is no networking involved, only the serial port.

What i need is a program that emulates an ANSI terminal inside my VT(XFCE terminal) and connected to the other side using serial cable to a computer.

I need something like telnet, but instead of using the TCP/IP i want to use a serial port.
