Hashes pt. 2
Let's take a hash
my %content = ( username => $ref->{username}, email => $ref->{email} );
Send a reference to the hash, along with other parameters, to some function
someFunc(\%content, $title);
Then unpack it at the other end
sub someFunc {
my ($contentRef, $title)=@_;
my %content = %$contentRef;
print $contentRef{username};
}
1;
