change the priority on the fly

alaios · 12-14-2004, 09:57 AM

Hi... I need to dynamically change the priority of a process.

For example assume that we have a process that consumes a lot of cpu... I want to send a signal to the process and change the priority to a higher number, without killing it and starting again from start.
Any ideas?
Thx a lot

On command line / script

Code:

renice

Or on the source:

Code:

int setpriority(int wich, int who, int prio)

(Check the man pages)
