controlling SWAP mem and CPU Utilization thru C coding..disabling multi-user mode
Posted on 2003-03-29
I have a multi-threaded application(3 threads to be precise and 1 root thread)developed in C on linux..When i run this application, two threads use quite large amt of of CPU resources and abt 126 MB of my 128 MB RAM while swap is not at all used..Is it possible to include the code for controlling balance between swap and RAM being used in the application or is it some setting within some linux files????And how is possible to decrease the CPU utilization???
One more thing..i start my application using a shell script..i want whenever that shell script runs, user should be able to switch betwen screens using Ctrl-Alt-F1, etc(to disable multi-user mode)..How can that be done??i am able to find trapping interrupts like Ctrl Z but not this..
