NAME
FFI::Raw::Callback - FFI::Platypus::Legacy::Raw function pointer type
VERSION
version 0.04
DESCRIPTION
A FFI::Raw::Callback represents a function pointer to a Perl routine. It can be passed to functions taking a FFI::Raw::ptr
type.
CONSTRUCTOR
new
my $callback = FFI::Raw::Callback->new( $coderef, $ret_type, @arg_types );
Create a FFI::Raw::Callback
using the code reference $coderef
as body. The signature (return and arguments types) must also be passed.
CAVEATS
For callbacks with a FFI::Raw::str
return type, the string value will be copied to a private field on the callback object. The memory for this value will be freed the next time the callback is called, or when the callback itself is freed. For more exact control over when the return value is freed, you can instead use FFI::Raw::ptr
type and return a FFI::Raw::MemPtr object.
