Newbie array filling question

[Steve George]

Hi,

When I initialise an auto array I often want to fill it with a default value 
rather than leave the junk in it.  At the moment I write a loop to run 
through the array and fill it with a number/char but I was wondering if there 
is a standard lib func to do this?

This applies for both char and int arrays.

I checked http://www.telespace.ch/libc/ but can't find anything obvious.

TIA,

Steve
