X11::Auth - Perl module to read X11 authority files |
NAME
X11::Auth - Perl module to read X11 authority files
SUPPORTED PLATFORMS
- Linux
- Solaris
- Windows
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().
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
