this class gives access to some operating system services;
|
|
|
314 |
some of it is very specific for unix, so do not depend on
|
|
|
315 |
things available here in your applications - some may not
|
|
370
|
316 |
be found in other OS's or be slightly different ...
|
|
216
|
317 |
Currently, there is only this class available - once more than
|
|
|
318 |
Unix is supported, the corresponding class will be bound to the
|
|
|
319 |
global variable OperatingSystem.
|
|
68
|
320 |
|
|
|
321 |
(On the other hand: I do not want to hide all features
|
|
|
322 |
from you - in some situations it MAY be interresting to be
|
|
|
323 |
able to get down to a select or fork system call easily.
|
|
|
324 |
You decide - portability vs. functionality)

non-SYSV4 systems have no age/comment.
|

1039 |
Portable applications may want to check the systemType and NOT depend

1040 |
on all keys to be present in the returned dictionary.

Another notice: on some systems (SYSV4), the gecos field includes multiple

1042 |
entries (i.e. not just the name), separated by commas. You may want to
|
|
|
1043 |
extract any substring, up to the first comma to get the real life name."
