Programs such as <EM>ps</EM>, <EM>top</EM>, and <TT>free</TT> must have some way
|
||
|
to obtain information from the kernel about a processes and system
|
||
|
resources. Similarly, debuggers and other like tools need the ability
|
||
|
to control and inspect a running process. These features have been
|
||
|
provided by a number of interfaces by different versions of UNIX,
|
||
|
and nearly all of them are either machine-specific or tied to a
|
||
|
particular kernel design. So far, there has been no universally-accepted
|
||
|
interface for this kind of process-kernel interaction.
