The version of Win32::Pipe on CPAN (and in ActivePerl) may be a different
version than the one mentioned on Dave’s website. You
should check out the sample program included in Win32-Pipe to see how it works:

when I run this simple client program
use strict;
use warnings;
use Win32::Pipe;
my $Data;
Win32::Pipe::CallNamedPipe(".\\Pipe\\EPICIPCDPLX", "3", $Data);

I get this error;

String literals are usually delimited by either single or double quotes.
They work much like quotes in the
standard Unix shells: double-quoted string literals are subject to
backslash and variable substitution;
single-quoted strings are not (e
There's a pretty good explanation of it here:

Specifically this part:
* The sequence \' yields the character ' in the actual string. (This is the
exception we already discussed above).
* The sequence \\ yields the character \ in the
Here's my take:
print 'it\'s time \\ to go';
The backslash can quote the single-quote, and hence another backslash as
well for completeness, within a single-quoted string.

interpreted by perl in an unaltered manner.
sample code, indicating how to reference a named pipe in the Win32::Pipe
module, shows something like this.
