NAME

PDK::OSType - Constants for platform specific conditional code

SYNOPSIS

use PDK::OSType qw(IS_WIN32);

if (IS_WIN32) {
   # do windows specific code
}
else {
   # do other code
}

DESCRIPTION

This module exports the constants IS_WIN32 and IS_UNIX. These constants can be used to wrap conditional code for specific platforms. Using these constants instead of testing $^O directly allow perl to eliminate unused branches of the code at compile time. Thus

if (IS_WIN32) {
    ...
}

is exactly the same as

if ($^O eq "MSWin32") {
    ...
}

but the first form looks better and the whole block is eliminated at compile time if not running on a windows machine. The test:

if (IS_UNIX) { ... }

is currently the same as

if ($^O ne "MSWin32") { ... }

but this might change in the future if Komodo is made to support systems other than Windows and Unix. There is no simple $^O test that can determine if the OS is Unix.
