FFI::Platypus::Function#

An FFI function object

VERSION#

version 2.12

SYNOPSIS#

use FFI::Platypus 2.00;

# call directly
my $ffi = FFI::Platypus->new( api => 2 );
my $f = $ffi->function(puts => ['string'] => 'int');
$f->call("hello there");

# attach as xsub and call (faster for repeated calls)
$f->attach('puts');
puts('hello there');

DESCRIPTION#

This class represents an unattached platypus function. For more context and better examples see FFI::Platypus.

METHODS#

attach#

$f->attach($name);
$f->attach($name, $prototype);

Attaches the function as an xsub (similar to calling attach directly from an FFI::Platypus instance). You may optionally include a prototype.

call#

my $ret = $f->call(@arguments);
my $ret = $f->(@arguments);

Calls the function and returns the result. You can also use the function object like a code reference.

sub_ref#

my $code = $f->sub_ref;

Returns an anonymous code reference. This will usually be faster than using the call method above.
