     my $intarraysize = $ffi->sizeof('int[64]');  # usually 4*64
     my $intarraysize = $ffi->sizeof('long[64]'); # usually 4*64 or 8*64
                                                  # depending on platform

    Keep in mind that "pointer" types will always be the pointer / word
    size for the platform that you are using. This includes strings, opaque
    and pointers to other types.

    This function is not very fast, so you might want to save this value as
    a constant, particularly if you need the size in a loop with many
    iterations.

 alignof

    [version 0.21]

     my $align = $ffi->alignof($type);

    Returns the alignment of the given type in bytes.
