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;

    1;

    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.
