Имя (Name)

pam_xauth_data - structure containing X authentication data

Синопсис (Synopsis)

#include <security/pam_appl.h>

struct pam_xauth_data { int namelen; char *name; int datalen; char *data; };


Описание (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.
