<title>DESCRIPTION</title>
71
This program reads a password from a <acronym>FIFO</acronym> and
72
outputs it to standard output.
75
This program is not very useful on its own. This program is
76
really meant to run as a plugin in the <application
77
>Mandos</application> client-side system, where it is used as a
78
fallback and alternative to retrieving passwords from a
79
<application >Mandos</application> server.
82
This program is meant to be imitate a feature of the
83
<command>askpass</command> program, so that programs written to
84
interface with it can keep working under the
85
<application>Mandos</application> system.

<title>EXIT STATUS</title>

If exit status is 0, the output from the program is the password
100
as it was read. Otherwise, if exit status is other than 0, the
101
program was interrupted or encountered an error, and any output
102
so far could be corrupt and/or truncated, and should therefore

will read the password. If it does not exist, it will be

The only thing that could be considered worthy of note is
150
this: This program is meant to be run by <citerefentry>
151
<refentrytitle>plugin-runner</refentrytitle><manvolnum
152
>8mandos</manvolnum></citerefentry>, and will, when run
153
standalone, outside, in a normal environment, immediately output
154
on its standard output any presumably secret password it just
155
received. Therefore, when running this program standalone
156
(which should never normally be done), take care not to type in
157
any real secret password by force of habit, since it would then
158
immediately be shown as output.
