NAME

FFI::Raw::Ptr - Base FFI::Raw pointer type

VERSION

version 0.32

SYNOPSIS

package Foo;

use FFI::Raw;

use base qw(FFI::Raw::Ptr);

*_foo_new = FFI::Raw -> new(
  $shared, 'foo_new',
  FFI::Raw::ptr
) -> coderef;

sub new {
  bless shift -> SUPER::new(_foo_new());
}

*get_bar = FFI::Raw -> new(
  $shared, 'foo_get_bar',
  FFI::Raw::int,
  FFI::Raw::ptr
) -> coderef;

*set_bar = FFI::Raw -> new(
  $shared, 'foo_set_bar',
  FFI::Raw::void,
  FFI::Raw::ptr,
  FFI::Raw::int
) -> coderef;

*DESTROY = FFI::Raw -> new(
  $shared, 'foo_free',
  FFI::Raw::void,
  FFI::Raw::ptr
) -> coderef;

package main;

my $foo = Foo -> new;

$foo -> set_bar(42);

DESCRIPTION

A FFI::Raw::Ptr represents a pointer to memory which can be passed to functions taking a FFI::Raw::ptr argument.

Note that differently from FFI::Raw::MemPtr, FFI::Raw::Ptr pointers are not automatically deallocated once not in use anymore.

METHODS

new( $ptr )

Create a new FFI::Raw::Ptr pointing to $ptr, which can be either a FFI::Raw::MemPtr or a pointer returned by a C function.
