4 | * Huge Nasty Error Table | |
5 | * | |
6 | * Plan 9 uses error strings, Unix uses error numbers. This table tries to | |
7 | * match UNIX strings and Plan 9 strings to unix error numbers. It is used | |
8 | * to preload the dynamic error table which can also track user-specific error | |
9 | * strings. | |
