how to write my own code for the command "who" in unix

 

[bi]

You mean write code that would do the same thing that who does? Why would you need to do that when it is already part of just about all (if not all) flavors of Unix? Sort of like reinventing the wheel, isn't it?

What have you tried?

Have you included utmp.h and/or utmpx.h and used the struct utmp(x) to read the records into?

There are a whole suite of functions designed to read from these databases. See man getutxent for example.
