Change priority of the current process in C

Question

On Windows I can do:

HANDLE hCurrentProcess = GetCurrentProcess();

SetPriorityClass(hCurrentProcess, ABOVE_NORMAL_PRIORITY_CLASS);

How can I d

Answer 1

If doing something like this under unix your want to (as root) chmod you task and set the s bit. Then you can change who you are running as, what your priority is, your thread scheduling, etc. at run time.

It is great as long as you are not writing a massively multithreaded app with a bug in it so that you take over a 48 CPU box and nobody can shut you down because your have each CPU spinning at 100% with all thread set to SHED_FIFO (runs to completion) running as root.

Nah .. I wouldn't be speaking from experience ....
