Hi!

It is feasible to execute external programs as another user (not
current user, linux)?

Sorry my poor english!

Yes, in linux you can fpfork() and in the "client" (result > 0) you
can fpsetpid(userpid). But this only works if you have the rights for
such things, which usually you won't.

This works if I was worth it well simply, the application than Root I
run it.
For me in that direction would be my need, that I ask for Root
password from the user, and the exterior program than Root I run it.

Sorry my english! I did translating with webforditas.hu help.

Thanks!
