NAME

       X11::Auth - Perl module to read X11 authority files

SYNOPSIS

         require X11::Auth;
         $a = new X11::Auth;
         ($auth_type, $auth_data) = $a->get_by_host($host, $disp_num);

DESCRIPTION

       This module is an approximate perl replacement for the libXau C library and the xauth(1)
       program. It reads and interprets the files (usually '~/.Xauthority') that hold
       authorization data used in connecting to X servers. Since it was written mainly for the
       use of X11::Protocol, its functionality is currently restricted to reading, not writing,
       of these files.

METHODS

   new
         $auth = X11::Auth->new;
         $auth = X11::Auth->open($filename);

       Open an authority file, and create an object to handle it. The filename will be taken from
       the XAUTHORITY environment variable, if present, or '.Xauthority' in the user's home
       directory, or it may be overridden by an argument. 'open' may be used as a synonym.

   get_one
         ($family, $host_addr, $display_num, $auth_name, $auth_data)
            = $auth->get_one;

       Read one entry from the file. Returns a null list at end of file.  $family is usually
       'Internet' or 'Local', and $display_num can be any string.

   get_all
         @auth_data = $auth->get_all;

       Read all of the entries in the file. Each member of the array returned is an array ref
       similar to the list returned by get_one().

   get_by_host
         ($auth_name, $auth_data)
            = $auth->get_by_host($host, $family, $display_num);

       Get authentication data for a connection of type $family to display $display_num on $host.
       If $family is 'Internet', the host will be translated into an appropriate address by
       gethostbyname(). If no data is found, returns an empty list.

COMPATIBILITY

       The following table shows the (rough) correspondence between libXau calls and X11::Auth
       methods:

         libXau                     X11::Auth
         ------                     ---------
         XauFileName                $ENV{XAUTHORITY}
                                    || "$ENV{HOME}/.Xauthority"
         fopen(XauFileName(), "rb") $auth = new X11::Auth
         XauReadAuth                $auth->get_one
         XauWriteAuth
         XauGetAuthByAddr           $auth->get_by_host
         XauGetBestAuthByAddr
         XauLockAuth
         XauUnlockAuth
         XauDisposeAuth
