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.
