NAME

       AppConfig::Sys - Perl5 module defining platform-specific information and methods for other
       AppConfig::* modules.

SYNOPSIS

           use AppConfig::Sys;
           my $sys = AppConfig::Sys->new();

           @fields = $sys->getpwuid($userid);
           @fields = $sys->getpwnam($username);

OVERVIEW

       AppConfig::Sys is a Perl5 module provides platform-specific information and operations as
       required by other AppConfig::* modules.

       AppConfig::Sys is distributed as part of the AppConfig bundle.

DESCRIPTION

   USING THE AppConfig::Sys MODULE
       To import and use the AppConfig::Sys module the following line should appear in your Perl
       script:

            use AppConfig::Sys;

       AppConfig::Sys is implemented using object-oriented methods.  A new AppConfig::Sys object
       is created and initialised using the AppConfig::Sys->new() method.  This returns a
       reference to a new AppConfig::Sys object.

           my $sys = AppConfig::Sys->new();

       This will attempt to detect your operating system and create a reference to a new
       AppConfig::Sys object that is applicable to your platform.  You may explicitly specify an
       operating system name to override this automatic detection:

           $unix_sys = AppConfig::Sys->new("Unix");

       Alternatively, the package variable $AppConfig::Sys::OS can be set to an operating system
       name.  The valid operating system names are: Win32, VMS, Mac, OS2 and Unix.  They are not
       case-specific.

   AppConfig::Sys METHODS
       AppConfig::Sys defines the following methods:

       getpwnam()
           Calls the system function getpwnam() if available and returns the result.  Returns
           undef if not available.  The can_getpwnam() method can be called to determine if this
           function is available.

       getpwuid()
           Calls the system function getpwuid() if available and returns the result.  Returns
           undef if not available.  The can_getpwuid() method can be called to determine if this
           function is available.
