perl function getpriority

The getpriority function in Perl is used to retrieve the priority of a specified process or process group.

Here's an example of using getpriority in Perl:

#!/usr/bin/perl

use strict;
use warnings;

# Get the priority of the current process
my $priority = getpriority(0, $$);

print "Priority: $priority\n";

In this example, we call the getpriority function to retrieve the priority of the current process. The first argument to getpriority specifies the type of process entity to query (0 for a process, 1 for a process group). The second argument specifies the ID of the process or process group to query. In this case, we use the special variable $$ to specify the process ID of the current process.

The priority value returned by getpriority is then printed to the console using the print function.

When you run this script, it will print the priority of the current process to the console.

Note that the behavior of getpriority may depend on the operating system and the specific process being queried. Additionally, it may be necessary to have appropriate privileges to access process priority information.
