implementation of rand() ?

[Skybuck Flying]

Hi,

What is the implementation of rand() on say visual c/c++ 5 or 6 ?

Another question... is this rand() implementation the same on any other
platforms/compilers/libraries ?

Where can I find/look at the implementation of rand() ?

Thx for any help.

Bye,
Skybuck.

He's ba-a-a-ck ... (A little Googling of SF's past,
er, "contributions" is suggested before replying.)

Well I have moved this discussion to sci.crypt etc... since it is more
relevant there...

See the thread:

'Hunt for rand and srand implementations'

So far I have found no implementations for visual c/c++ 6.0 (I think... I
should retry the ones I found )

I did find IBM_AIX and POSIX implementations...

Any other implementations are welcome especially for redhat, debian, etc...
I am not sure if those are the same...

Any links for finding linux source code for those distributions on the web
like cvs etc are welcome

Bye,
Skybuck.

If you hadn't commented I would never have noticed. I wouldn't
have regretted that either. To the tune of "That's what plonks are
for".

You having pulling this "verbose mode enabled" thing in various newsgroups
for years, that's not news.

See the thread:

Look, if you want a decent random number generator, and you don't
trust the one that comes with your compiler, google for "mersenne twister".

If you need one good enough for crypto, that's not it. Instead, take it
up with the gurus in sci.crypt. Either way, it's OT here.

The compiler comes with source code for the C runtime library. If you
installed your compiler with the source (or go back and reinstall it now),
just like in VC98\CRT\SRC\rand.c under whatever you directory you installed
the compiler to. You should know this already.

You think PRNG's care about the OS?

Any other implementations are welcome especially for redhat, debian, etc...
I am not sure if those are the same...
