|
|
* check-sizes -- Check sizes of structures and types
|
|
*
|
|
* Author: Roy Hills
|
|
* Date: 30 December 2003
|
|
*
|
|
* Check that the sizes of the various structs are what we expect them
|
|
* to be. If they are not, then we return with a failure status.
|
|
*
|
|
* There are several places in the ike-scan code where we copy structs
|
|
* to character arrays and vice versa. E.g. send_packet().
|
|
*
|
|
* Although this is not condoned in C, it is OK in practice
|
|
* providing that the sizes of the fields is correct and there is no
|
|
* padding between fields (e.g. for alignment purposes). This function
|
|
* checks for both of these problems.
