* The compatibility model is as follows. The current format should be retained
|
6 |
* for as long as possible; new fields can be added at the end of the line,
|
7 |
* because ps/top only read as much as they know of from the start of the line.
|
8 |
* Once fields (really) have to be removed, or the whole line becomes too big
|
9 |
* of a mess, a completely new format string can be put in, but with an
|
10 |
* increased PSINFO_VERSION at the beginning. That way, older ps/top copies
|
11 |
* will not misinterpret the new fields, but rather fail cleanly.
