NAME

       FFI::Platypus::Type::PointerSizeBuffer - Convert string scalar to a buffer as a pointer /
       size_t combination

VERSION

       version 0.47

SYNOPSIS

       In your C code:

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

       In your Platypus::FFI code:

        use FFI::Platypus;

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

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

DESCRIPTION

       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.  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.
