AutoIt structure with no padding.

[GarboBombo]

I think the title is self explanatory, but if not I just need a way of creating a structure has no padding if an array of bytes is less than 4. Although I know this specific and not at all efficient the task I am trying to accomplish is pretty stern when it comes to data structures. If there are any other alternatives for data structures when pertaining to specific size of variables I would be more than grateful to use that.

Just as an example I'll show a little bit of code to explain what my problem is.

#include <Misc.au3>
#include <Math.au3>
#include <WinAPI.au3>

$examplestruct = "BYTE base;"
$examplestruct&= "FLOAT s;"
$examplestruct&= "FLOAT d;"
$examplestruct&= "FLOAT a;"

$example = DllStructCreate($examplestruct)

MsgBox(1,"Structure Size Problem","Target size of structure: 13 bytes"&@CRLF&"Actual size of structure:"&DllStructGetSize($example)&" bytes")

To align is divine...

#include <Misc.au3>
#include <Math.au3>
#include <WinAPI.au3>

$examplestruct = "align 1;BYTE base;"
$examplestruct&= "FLOAT s;"
$examplestruct&= "FLOAT d;"
$examplestruct&= "FLOAT a;"

$example = DllStructCreate($examplestruct)

MsgBox(1,"Structure Size Problem","Target size of structure: 13 bytes"&@CRLF&"Actual size of structure:"&DllStructGetSize($example)&" bytes")

Truly! Thank you.
