FFI::Platypus::Function(3)

NAME
FFI::Platypus::Function - An FFI function object

VERSION
version 2.10

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.
