⭐ VERSION ⭐

version 2.11 β€” that's the version, no cap πŸ’€

πŸŽ€ SYNOPSIS πŸŽ€

In your C code:

void
function_with_buffer(void *pointer, size_t size)
{
  ...
}

In your Platypus::FFI code:

use FFI::Platypus 2.00;

my $ffi = FFI::Platypus->new( api => 2 );
$ffi->load_custom_type('::PointerSizeBuffer' => 'buffer');

$ffi->attach(function_with_buffer => ['buffer'] => 'void');
my $string = "content of buffer";
function_with_buffer($string);

πŸ’– DESCRIPTION πŸ’–

A common pattern in C code is to pass in a region of memory as a buffer, consisting of a pointer and a size of the memory region. that's literally the C flex: pointer + size, holding hands 🫢

In Perl, string scalars also point to a contiguous series of bytes that has a size, so when interfacing with C libraries it is handy to be able to pass in a string scalar as a pointer / size buffer pair. this type is the little matchmaker that lets that happen πŸ’–
