=head1 NAME

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

=head1 VERSION

version 0.32

=head1 DESCRIPTION

A B<FFI::Raw::Callback> represents a function pointer to a Perl routine. It can
be passed to functions taking a C<FFI::Raw::ptr> type.

=head1 METHODS

=head2 new( $coderef, $ret_type [, $arg_type ...] )

Create a C<FFI::Raw::Callback> using the code reference C<$coderef> as body. The
signature (return and arguments types) must also be passed.

=head1 CAVEATS

For callbacks with a C<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 C<FFI::Raw::ptr> type and return a L<FFI::Raw::MemPtr> object.
