* IMPORTANT:
|
* All structures below are designed to be the same size when compiled for 32
|
* and/or 64 bit architectures, i.e. there should be no compiler inserted
|
* padding. This is achieved by sticking to the following rules:
|
* 1) only use fixed width types
|
* 2) always naturally align fields by arranging them appropriately and by using
|
* padding fields when necessary
|
*
|
* These rules should _always_ be followed when modifying or adding new
|
* structures to this file.
