Passing filehandles to subs.by r.joseph (Hermit)
|on May 05, 2001 at 12:16 UTC||Need Help??|
r.joseph has asked for the
wisdom of the Perl Monks concerning the following question:
Really quick question. When passing around filehandles between subs, what is the difference between:
and a very slight change:
As you can see, in the first example it seems that I have passed a glob reference to the sub, while in the second example I have simply passed the glob. Both work exactly the same, yet I have seen both - what is the difference (is one advantageous over the other)?
Also, what is the reason that if I protoype one() like this:
it doesn't work, but
does? I would think that using \* would just require a glob reference - where am I wrong?
Thanks for the help - these glob things are very new to me!
