getpriority

See the current Perl documentation for getpriority.

Here is our local, out-dated (pre-5.6) version:

getpriority - get current nice value

getpriority WHICH,WHO

Returns the current priority for a process, a process group, or a user. (See getpriority(2).) Will raise a fatal exception if used on a machine that doesn't implement getpriority(2).
