The Question is:
Hi,
Can a process with correct privleges suspend another process on a different
user's terminal and spawn a process on that user's terminal? If so how would
I go about doing so. Say for example, spawing a custom login screen for that
user (third party) an
d upon exiting (after logging in) continue the process that was running. I am
tring to create a screen saver with a custom login screen that will prompt the
user without editing the source of the program I want to suspend / continue.
I have a program ma
de already that will detect when a process is not being used and run a FORCEX
on that process. I would like to replace the FORCEX with code that will
suspend that process and run the custom login program under that user.
Basicly : suspend A, run B, finish B, continue A
Thanks!
The Answer is :
This is not an easy task, and the state of the various I/O channels
involved can very easily become confused -- what you want to perform
generally requires the direct assistance of the client application,
either within the application itself or within supporting command
procedures.
The usual solution here is a client-server implementation, and
providing a layer between the running application and the user's
display.
