Apostrophe in subroutine call
|
Can't Post

|
Hi,
I'm trying to understand a bit of opensource perl and I have come across something I have never seen before. When various subroutines are called, they have an apostrophe somewhere in the middle of it, per (see underlined parts of code):
sub HttpInit
{
local($arg, $db, $pw, $headers, $agent) = @_;
defined &Http'Init || do {
unshift(@INC, $HOME);
require "linkhttp.pl";
};
&Http'Init($arg, $db, $pw, $headers, $agent);
}
This one calls itself! Does anyone know what this means or what it does? Examples of this are littered throughout this particular package. Any help is appreciated.
