PAM_XAUTH_DATA(3)                         Linux-PAM Manual                         PAM_XAUTH_DATA(3)



NAME
       pam_xauth_data - structure containing X authentication data

SYNOPSIS
       #include <security/pam_appl.h>

       struct pam_xauth_data {
           int namelen;
           char *name;
           int datalen;
           char *data;
       };


DESCRIPTION
       The pam_xauth_data structure contains X authentication data used to make a connection to an X
       display. Using this mechanism, an application can communicate X authentication data to PAM
       service modules. This allows modules to make a connection to the user's X display in order to
       label the user's session on login, display visual feedback or for other purposes.

       The name field contains the name of the authentication method, such as "MIT-MAGIC-COOKIE-1".
       The namelen field contains the length of this string, not including the trailing NUL
       character.

       The data field contains the authentication method-specific data corresponding to the
       specified name. The datalen field contains its length in bytes.

       The X authentication data can be changed with the PAM_XAUTH_DATA item. It can be queried and
       set with pam_get_item(3) and pam_set_item (3) respectively. The value used to set it should
       be a pointer to a pam_xauth_data structure. An internal copy of both the structure itself and
       its fields is made by PAM when setting the item.

SEE ALSO
       pam_start(3), pam_get_item(3),

STANDARDS
       The pam_xauth_data structure and PAM_XAUTH_DATA item are Linux-PAM extensions.
