20 The pam_xauth_data structure contains X authentication data used to
21 make a connection to an X display. Using this mechanism, an application
22 can communicate X authentication data to PAM service modules. This
23 allows modules to make a connection to the user's X display in order to
24 label the user's session on login, display visual feedback or for other
25 purposes.
26
27 The name field contains the name of the authentication method, such as
28 "MIT-MAGIC-COOKIE-1". The namelen field contains the length of this
29 string, not including the trailing NUL character.
30
31 The data field contains the authentication method-specific data
32 corresponding to the specified name. The datalen field contains its
33 length in bytes.
34
35 The X authentication data can be changed with the PAM_XAUTH_DATA item.
36 It can be queried and set with pam_get_item(3) and pam_set_item (3)
37 respectively. The value used to set it should be a pointer to a
38 pam_xauth_data structure. An internal copy of both the structure itself
39 and its fields is made by PAM when setting the item.

45 The pam_xauth_data structure and PAM_XAUTH_DATA item are Linux-PAM
