description
pkttyagent
is used to start a textual authentication agent for the
subject specified by either --process or
--system-bus-name. If neither
of these options are given, the parent process is used.
To get notified
when the authentication agent has been registered either
listen to the Changed D-Bus signal or use
--notify-fd to pass the number of a
file descriptor that has been passed to the program. This
file descriptor will then be closed when the authentication
agent has been successfully registered.
If
--fallback is used, the textual
authentication agent will not replace an existing
authentication agent.
notes
Since process identifiers can be recycled, the caller should
always use pid,pid-start-time when using the
--process option. The value of pid-start-time can
be determined by consulting e.g. the proc(5) file system
depending on the operating system. If only pid is passed
to the --process option, then pkttyagent will look
up the start time itself but note that this may be racy.
return value
If the authentication agent could not be registered,
pkttyagent exits with an exit code of 127. Diagnostic
messages are printed on standard error.
If one or more of the options passed are malformed,
pkttyagent exits with an exit code of 126. If stdin is a
tty, then this manual page is also shown.
If the authentication agent was successfully registered,
pkttyagent will keep running, interacting with the user as
needed. When its services are no longer needed, the process can
be killed.
