SYNOPSIS

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

DESCRIPTION

FFI::Platypus::Legacy::Raw and friends are a fork of FFI::Raw that uses FFI::Platypus instead of FFI::Raw's own libffi implementation. It is intended for use when migrating from FFI::Raw to FFI::Platypus. The main reason one might have for switching from Raw to Platypus is because Platypus is actively maintained, provides a more powerful interface, can be much faster when functions are "attached", and works on more platforms than Raw. This module should be a drop in replacement for FFI::Raw, simply replace all instances of FFI::Raw to FFI::Platypus::Legacy::Raw. See also Alt::FFI::Raw::Platypus for a way to use this module without making any source code changes.

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

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

CONSTRUCTOR

new

 my $ptr = FFI::Platypus::Legacy::Raw::Ptr->new( $ptr );

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