When you use popen you can ONLY read from the command's stdout
or ONLY write to it's stdin.
I you want both of them (and may be stderr too) you need play with
fork/exec/dup call's.

This is not something sudo specific it's pretty general for all commands,
which needs both input and output.

If you can (and want ) configure sudo to run this command without password
you'll need only read output from the sudo, i.e. popen will work for you
