<title>DESCRIPTION</title>
61
This program reads a password from a <acronym>FIFO</acronym> and
62
outputs it to standard output.
65
This program is not very useful on its own. This program is
66
really meant to run as a plugin in the <application
67
>Mandos</application> client-side system, where it is used as a
68
fallback and alternative to retrieving passwords from a
69
<application >Mandos</application> server.
72
This program is meant to be imitate a feature of the
73
<command>askpass</command> program, so that programs written to
74
interface with it can keep working under the
75
<application>Mandos</application> system.

<title>EXIT STATUS</title>

If exit status is 0, the output from the program is the password
90
as it was read. Otherwise, if exit status is other than 0, the
91
program was interrupted or encountered an error, and any output
92
so far could be corrupt and/or truncated, and should therefore

104
This is the <acronym>FIFO</acronym> where this program
105
will read the password. If it does not exist, it will be

Note that normally, this program will not be invoked directly,
117
but instead started by the Mandos <citerefentry><refentrytitle

134
The only thing that could be considered worthy of note is
135
this: This program is meant to be run by <citerefentry>
136
<refentrytitle>plugin-runner</refentrytitle><manvolnum
137
>8mandos</manvolnum></citerefentry>, and will, when run
138
standalone, outside, in a normal environment, immediately output
139
on its standard output any presumably secret password it just
140
received. Therefore, when running this program standalone
141
(which should never normally be done), take care not to type in
142
any real secret password by force of habit, since it would then
143
immediately be shown as output.
