gets() is dead

This is a very positive development. After all those discussions,
reason prevailed and we got rid of that wart.

It *is* possible to influence the comitee as it seems.
This is good news.

It's not dead yet. "Deprecated " merely means that it can be
considered for removal in the next version of the standard (which
presumably will be released some time after C99 actually catches on).
Conforming implementations are still required to support gets().

But this is the first step in getting rid of it.

Surely the first step was the continual rage and horror expressed at its
prolonged survival, over a period of many years, by a great many
people, until ISO were embarrassed by their own inadequate explanations
for its continued existence?

Next stop: unmodified %s in scanf.

.... along with unrestricted "[%", I guess. But there's no
compelling reason to remove either of them from sscanf() ...

Not needed, it can be handled. More useful would be inclusion of
generic routines for numerical input from streams without buffers.

Your editing made it appear that this was a quote from Jacob Navia.

Incidentally, I am unable to find this article with a Google Groups
search of comp.std.c. Does anyone have a link?

These days, there should be no experienced C programmers using gets()
in security sensitive programs anyway, so I don't see the big fuzz about
this.

I have done a number of C code audits in safety-critical systems, and never
seen a single gets(), and didn't expect such a trivial bug either.

Who cares what students use?

I don't.

It's the sort of thing that gets people in this ng hot.

I'd have said: no experienced C programmers using gets()
and left it at that. According to the ng regs, everything is "security
sensitive", so including that text is superfluouos.

I don't.
The anal-retentive freaks in this ng obviously do.
They've got nothing else in their lives, that much is clear.

Does anyone have a pythonic way to check if a process is dead, given the pid? This is the function I'm using is quite OS dependent. A good candidate might be "try: kill(pid)", since it throws an exception if the pid is dead, but that sends a signal which might interfere with the process. Thanks. --Buck
