pam_xauth_data - structure containing X authentication data
#include <security/pam_appl.h>
struct pam_xauth_data {
int namelen;
char *name;
int datalen;
char *data;
};
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.
pam_start(3),
pam_get_item(3),
The
pam_xauth_data structure and
PAM_XAUTH_DATA item are Linux-PAM
extensions.
