NAME

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

VERSION

version 2.05

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.
