/* MARS needs to report many issues to scripts and to humans.
|
||
|
|
* Many problems are not covered by POSIX and other errno definitions.
|
||
|
|
*
|
||
|
|
* IMPORTANT: keep the following namespaces unique within itself.
|
||
|
|
* Keep MARS-specific namespace parts distinct from POSIX and others:
|
||
|
|
* (a) Integer (primary key)
|
||
|
|
* (b) C preprocessor macro names
|
||
|
|
* (c) Cleartext intended for humans.
|
||
|
|
* Also, make any entry a 1:1:1 correspondence.
|
||
|
|
*
|
||
|
|
* While (a) and (b) are only defined here, the full
|
||
|
|
* relationship (a) <=> (b) <=> (c) should reside in marsadm.
