e_kit_patch.h
|
|
By Daniel Malmer
|
|
|
|
This file is used to allow customers to patch the Navigator binary
|
|
in the field.
|
|
The unique signature should only appear once in the Navigator. This
|
|
can be verified at Q/A time, but since it's 32 bytes long, that should
|
|
be sufficiently unique.
|
|
It works like this: e-kit is shipped with a patcher that recognizes
|
|
the signature below. Once it finds it, it knows that it's dealing with
|
|
the structure that holds the 'whacked' field, and can set it to '1'.
|
|
|
|
The SIGNATURE string should change any time there is a change made
|
|
to the data structure that is being touched. This way, lockers can't
|
|
patch Navigators that have different data structures.
|

/*
|
|
* HP-UX only defines this if XPG2 is defined.
|
|
* Until we figure out what the right thing to
|
|
* do is, 1024 looks like it will do.
|
|
* As long as the locker program and Navigator
|
|
* both use the same value, it should be fine.
