read of 0 byte file

What will happen if you read a file with 0 bytes?

say cat /dev/null > file

do a read on the file - what it should return -
So you expect error ??


It returns zero, which is success for read but no buffer is stored.

I had some tough time debugging this one.

So, Aware & Beware of this :)
