It works just the same a C except that C++ mangles function names so you must mark the functions you wish to call as extern "C". The functions can not be non-static member functions.

Thank you so much, I will try it.

Probably this is good for you? Regards, Karl

Thank you, but this method can be used for PDL array?

You'd need to use Inline with => 'PDL' to make available PDL's C functions. Then, to know what PDL C functions to actually call, consult PDL::API.

The imminent PDL::OpenCV (not on CPAN yet, but see https://github.com/PDLPorters/pdl/issues/362) shows how to call from PDL C code into C++ via a wrapper, if that's any use.

EDIT: "how to" is too strong - "one way to" would be better.

Hi toothedsword, I don‘t really know it and i’m not sure. I guessed. And i fear that you must try/figure it out yourself. Yet another experiment 😎 Best regards, Karl

perl -MCrypt::CBC -E 'say Crypt::CBC->new(-key=>'kgb',-cipher=>"Blowfish")->decrypt_hex($ENV{KARL});'Help

You may want to consider FFI::Platypus as opposed to more manual methods.

Good Luck, lbe

Thanks!
