hi

In comp.lang.c, "invalidating a port" is a meaningless phrase.

In /some/ operating environments, it /may/ mean to "close or disconnect a
communications channel", but it can just as easily mean to "write a known
bad value to a hardware I/O channel"

can i get a c program to validate a port

Not in comp.lang.c, you cant.

You can try comp.sources.wanted, or a newsgroup dedicated to your operating
system platform

That's *in*validating a port; the original poster asked about
*validating* a port.

"validating a port" is the process of checking that a program has
been successfully adapted from one platform / environment to
a different one.

When it comes to an entire compiler or similar program that has
behaviours defined by a standard, then a program to perform a
full or partial validation would be called a "conformance suite".

You can probably purchase a C conformance suite. The last time the
question arose, someone stated that there were definitely no free
(comprehensive?) C conformance suites; I have never looked for
one so I don't know.

Hi

what does validating a port means?

It could mean all sorts of things. A port can mean:

- a number used to differentiate which software on a machine should
deal with a messages received from a network

- a memory area or hardware address used by software to communicate
with some piece of hardware

- an implementation of a piece of software on a type of machine other
than the one it was written for

- or other things

"Validating" here means making sure something works or is ready to be
used. What that involves depends on what a port is.

can i get a c program to validate a port

If you mean can I download a c program to do this, then try google.

If you mean can I write a program to do it, then yes, but it will be
difficult. You need to work out what sort of port you mean, and then
find a group that is suited to programming for that sort of thing.
When you post there, give much more detail regarding what you mean and
what your situation is. Usenet readers cannot read your mind!

So is "validating a port", which is what he asked about.

Right. (But is comp.sources.wanted still alive?)

No, it isn't. Yet another reason to ask C-related questions in a C
newsgroup.

Oops...

Of course, you are correct.

My apologies

The subject came up recently in comp.compilers:
