|
* Object Implementation Notes:
|
|
*
|
|
* Allocating a new object creates an object header and a block of
|
|
* uninitialized user data. A pointer to this uninitialized data is
|
|
* returned to the user. The structure looks as follows:
|
|
*
|
|
* +--------------------+
|
|
* | MAGIC HEADER |
|
|
* | (object header) |
|
|
* +--------------------+
|
|
* | user data | -- pointer returned from PKIX_PL_Object_Alloc
|
|
* +--------------------+
|
|
*
|
|
* Object operations receive a pointer to raw user data as an argument.
|
|
* The macro HEADER(object) returns a pointer to the object header.
|
|
* An assertion then verifies that the first field is the MAGIC_HEADER.
