arand()

[Pierre McCann]

Howdy:

I am working on some code (written by someone else), and this line cropped
up:

newParameters.row = currentParameters.row + (temp *
step.row * arand());

My questions are:
1. What is the arand() function?
2. How is it different from the rand() function?
3. Is there a reference on the web that can be consulted for this
information?
Note on question #3: I'm not just asking without looking. I did have a
quick look around, but no searches on "arand" or "arand()" seemed to give me
what I was looking for.

Thanks in advance for any help.

Regards,

pdm

It's not standard C. Try asking on a newsgroup which discusses
whatever platform this came from.

It is not a standard C function, and therefore unfortunately off-topic
in c.l.c. Furthermore, I never came across it, AFAICT.

2. How is it different from the rand() function?

It has an 'a' prepended. No, seriously: I don't have a clue.

3. Is there a reference on the web that can be consulted for this
information?

If it's part of a known extension library, a Google search should help.

Well, in that case you should search the code you are working on and the
libraries it uses (read: inspect the header files it includes). If this
doesn't reveal any useful information, asking in a newsgroup dedicated
to your implementation/OS/platform might help.

Thanks in advance for any help.

Sorry for being unable to help any further, good luck to you.

You need to work on your googling skills. Try searching for "random number
generator arand" and see what it get s you. Regardless, it is not part of
the C standard and there appears to be more than one answer.

It is the rand() function called by a dyslectic Canadian, eh.
