Try the apropos command with your keywords - i.e.

apropos cpu usage

Code:

www# man apropos 
apropos(1)                                             apropos(1)

NAME
       apropos - search the whatis database for strings

SYNOPSIS
       apropos keyword ...

DESCRIPTION
       apropos  searches a set of database files containing short descriptions of
       system commands for keywords and displays the result on the standard  out-
       put.

SEE ALSO
       whatis(1), man(1).

You may use the "top" command.

Thanks.

I've writing a network management system with RPC to monitor the system status of a remote server. That's why I need those functions needed on the server side program.

The "top command" is not a C programming "function", it is a utility.

In your original post, you asked for a function for a C program you were writing.

How does top, which is a command line utility, help?

I know top is command in unix. But my project is to implement such a utility like top with RPC, which could be executed remotely. So on the RPC server side I need those C library functions or UNIX system calls that provide those information. But I don't their name and can't find them. But the professor said they exist and encourage us to find them through any methods. So I ask for the help here.

I'm still trying to find them out .....

Thanks!
