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