Hello,

I would like to add straight forward wrapper for the setpriority and getpriority functions to posixmodule.c for the os module. The functions allow to retrieve and modify the niceness of a process. They are in particular useful for multiprocessing to implement low priority processes. The functions are well known as 'nice' or 'renice' commands.

The two functions and the constants PRIO_PROCESS, PRIO_PGRP, PRIO_USER, PRIO_MIN and PRIO_MAX should be available on most POSIX operating systems. A patch would come with autoconf tests for the feature.

I don't think there's likely to be much controversy about putting these in.

Variants for Windows with roughly equivalent meanings would be nice. It looks pretty straightforward with pywin32, but someone with ctypes experience may be preferred. - Josiah

Wouldn't it be better to add these functions to the 'resource' module?

'resource' is Unix specific, but Josiah indicates Windows equivalents to set/getpriority are possible. In that case it seems like it belongs in posix/os since it can eventually be made cross-platform. -- R. David Murray http://www.bitdance.com
