Question on popen

[nkumar85]

Hello All,

Is it possible to use popen for multiple piping.

Ex: If I want to achieve "last | sort | wc -l" command using popen, how to do it?

Is it possible?

Thanks in advance
Nanda

No, you can't.
You'll have to use dup(), fork() and exec().

It should provide you with the basics. Then you will need to adapt to your needs.
