NAME ^

FFI::Raw::Callback - FFI::Raw function pointer type

VERSION ^

version 0.32

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.

METHODS ^

new( $coderef, $ret_type [, $arg_type ...] )

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.
