Hi, I want to call a dll, which requires a pointer to an array of doubles, followed by the length, or number of elements, in the array. I've created my object like:

my $obj = Win32::API->new("dll","Function", [P, I], I);

The problem is, I don't know how to set up the array for the call. I've tried:

$arr=pack("d",1) . pack("d",1.5), pack("d",3);

and

@arr=(pack("d3",1,1.5,3))

whatever I try causes perl.exe to crash (ActivePerl 5.6.1). Any ideas on how the call should be made would be appreciated
