|
* The "environment" is stored as a list of '\0' terminated
|
|
|
|
* "name=value" strings. The end of the list is marked by a double
|
|
|
|
* '\0'. New entries are always added at the end. Deleting an entry
|
|
|
|
* shifts the remaining entries to the front. Replacing an entry is a
|
|
|
|
* combination of deleting the old value and adding the new one.
|
|
|
|
*
|
|
|
|
* The environment is preceeded by a 32 bit CRC over the data part.
