perl::ostype
Perl::OSType(3perl) Perl Programmers Reference Guide Perl::OSType(3perl)
NAME
Perl::OSType - Map Perl operating system names to generic types
VERSION
version 1.002
SYNOPSIS
use Perl::OSType ':all';
$current_type = os_type();
$other_type = os_type('dragonfly'); # gives 'Unix'
DESCRIPTION
Modules that provide OS-specific behaviors often need to know if the current operating system matches a more generic type of operating
systems. For example, 'linux' is a type of 'Unix' operating system and so is 'freebsd'.
This module provides a mapping between an operating system name as given by $^O and a more generic type. The initial version is based on
the OS type mappings provided in Module::Build and ExtUtils::CBuilder. (Thus, Microsoft operating systems are given the type 'Windows'
rather than 'Win32'.)
USAGE
No functions are exported by default. The export tag ":all" will export all functions listed below.
os_type()
$os_type = os_type();
$os_type = os_type('MSWin32');
Returns a single, generic OS type for a given operating system name. With no arguments, returns the OS type for the current value of $^O.
If the operating system is not recognized, the function will return the empty string.
is_os_type()
$is_windows = is_os_type('Windows');
$is_unix = is_os_type('Unix', 'dragonfly');
Given an OS type and OS name, returns true or false if the OS name is of the given type. As with "os_type", it will use the current
operating system as a default if no OS name is provided.
