</tt>
-- Portable password input
</A>
<A NAME=
"module-getpass"></A>
The
<tt class=
"module">getpass
</tt> module provides two functions:
<dl><dt><table cellpadding=
"0" cellspacing=
"0"><tr valign=
"baseline">
<td><nobr><b><tt id='l2h-
1994' xml:id='l2h-
1994'

"function">getpass
</tt></b>(
</nobr></td>
<td><var></var><big>[
</big><var>prompt
</var><big>]
</big><var></var>)
</td></tr></table></dt>
Prompt the user for a password without echoing. The user is
prompted using the string
<var>prompt
</var>, which defaults to
<code>'Password: '
</code>.
Availability: Macintosh,
<span class=
"Unix">Unix
</span>, Windows.
<dl><dt><table cellpadding=
"0" cellspacing=
"0"><tr valign=
"baseline">
<td><nobr><b><tt id='l2h-
1995' xml:id='l2h-
1995'
class=
"function">getuser
</tt></b>(
</nobr></td>
<td><var></var>)
</td></tr></table></dt>
Return the ``login name'' of the user.
Availability:
<span class=
"Unix">Unix
</span>, Windows.
This function checks the environment variables
<a class=
"envvar" id='l2h-
1996' xml:id='l2h-
1996'
>LOGNAME
</a>,
<a class=
"envvar" id='l2h-

1997'
>USER
</a>,
<a class=
"envvar" id='l2h-
1998' xml:id='l2h-
1998'
>LNAME
</a> and
<a class=
"envvar" id='l2h-
1999' xml:id='l2h-
1999'
>USERNAME
</a>, in order, and
returns the value of the first one which is set to a non-empty
string. If none are set, the login name from the password database
is returned on systems which support the
<tt class=
"module"><a href=
"module-pwd.html">pwd
</a></tt> module,
otherwise, an exception is raised.
