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
