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.
