Usage:

First you need to declare the functions and types that you will be using:

$win32_idl <<GetTickCount();

echo $ffi->MessageBoxA(0, "The tick count is " . $count, "Ticky Ticky", 1);

Structures:

===========

You can declare structures in your ffi IDL using C style syntax.

Structure support is read-only for the moment.  You can pass structures

to functions and return them (these two examples work on linux):

Passing structs:

gettimeofday($tv, $tz) );

printf("tv_sec=%d tv_usec=%d\n", $tv->tv_sec, $tv->tv_usec);

?>

Returning Structs:

gethostbyname("localhost");

printf("h_length=%d h_name=%s\n", $he->h_length, $he->h_name);

?>

Tips:

For functions that expect to copy/store memory into a buffer, use

str_repeat() to "allocate" room for that buffer.
