15 pkttyagent is used to start a textual authentication agent for the
16 subject specified by either --process or --system-bus-name. If neither
17 of these options are given, the parent process is used.
18
19 To get notified when the authentication agent has been registered
20 either listen to the Changed D-Bus signal or use --notify-fd to pass
21 the number of a file descriptor that has been passed to the program.
22 This file descriptor will then be closed when the authentication agent
23 has been successfully registered.
24
25 If --fallback is used, the textual authentication agent will not
26 replace an existing authentication agent.
27
29 If the authentication agent could not be registered, pkttyagent exits
30 with an exit code of 127. Diagnostic messages are printed on standard
31 error.
32
33 If one or more of the options passed are malformed, pkttyagent exits
34 with an exit code of 126. If stdin is a tty, then this manual page is
35 also shown.
36
37 If the authentication agent was successfully registered, pkttyagent
38 will keep running, interacting with the user as needed. When its
39 services are no longer needed, the process can be killed.
40
42 Since process identifiers can be recycled, the caller should always use
43 pid,pid-start-time when using the --process option. The value of
44 pid-start-time can be determined by consulting e.g. the proc(5) file
45 system depending on the operating system. If only pid is passed to the
46 --process option, then pkttyagent will look up the start time itself
47 but note that this may be racy.
