<h2>Description</h2>
|
||
|
|
|
||
|
|
<p>The <tt>ar</tt> utility creates and maintains groups of files
|
||
|
|
combined into a library. Once a library has been created, you can
|
||
|
|
add new files, and extract, delete, or replace existing files.</p>
|
||
|
|
|
||
|
|
<h2>Exit status</h2>
|
||
|
|
|
||
|
|
<p><tt>ar</tt> exits with one of the following values:</p>
|
||
|
|
|
||
|
|
<table>
|
||
|
|
<tr><td valign="top">0</td>
|
||

<td valign="top">Successful completion.</td></tr>

<td>An error occurred.</td></tr>

<h2>Bugs</h2>
|
||
|
|
|
||
|
|
<p>No known bugs, but <em>please</em> read the comments in the code if
|
||
|
|
you want to use it in another application.</p>
|
||
|
|
|
||
|
|
<h2>Comments</h2>
|
||
|
|
|
||
|
|
<p>This is a POSIX 1003.2-1992 based <tt>ar</tt> command; it's not
|
||
|
|
100% POSIX 1003.2 because POSIX specifies a file format for
|
||
|
|
<tt>ar</tt> archives. The BeOS <tt>ar</tt> produces library files
|
||
|
|
compatible (at least in theory <tt>:-)</tt>) with Metrowerks
|
||
|
|
CodeWarrior for PowerPC.</p>
|
||
|
|
|
||
|
|
<p>This <tt>ar</tt> and its source code were written as a service to
|
||
|
|
the Be developer community, to make it easier for us to port UNIX
|
||
|
|
applications and libraries. The code was written from scratch, after
|
||
|
|
reverse-engineering the Metrowerks library and object file format
|
||
|
|
(mostly because the library/object file format documentation was
|
||
|
|
incorrect).</p>
|
||
|
|
|
||
|
|
<p>If you find this useful, please
|
||
|

<a href="mailto:chrish@kagi.com">let me know</a>, and tell me what
|
||
|
|
you're working on. Be sure to include a URL for your homepage or your

product homepages for my

|
||
|
|
pages.</p>
|
||
|
|
|
||
|
|
<p>If you find any bugs, please try to fix them, and send me a context
|
||
|
|
diff (use <tt>diff -c original_file fixed_file</tt>) so I can include
|
||
|
|
your fixes in the next update. I <i>have</i> tested this, but these
|
||
|
|
things have a way of slipping though.</p>
|
||
|
|
|
||
|

You can do whatever you want with it.</p>

<p>If you <em>really</em> want to show your appreciation, you could

always send me a gift of some sort; cool software you wrote, nice

pictures for my desktop, ZIP drive disks, RAM, hard drives, post

cards, a pointer to a really cool/useful/interesting web site,

know where to send it.</p>
|

<p>But you don't have to do anything. Just write good BeOS software.

But you're already doing that, right?</p>

<h2>Disclaimer</h2>
|
||
|
|
|
||
|
|
<p>You use this at your own risk. I've tried to ensure that the code
|
||
|
|
is correct, but software usually has bugs. If <tt>ar</tt> destroys
|
||
|
|
your valuable data, formats your hard drive, kicks your cat, and lets
|
||
|
|
the air out of your tires, I'm not responsible for it. The code is
|
||
|
|
here, so you should feel fairly safe that there's nothing evil going
|
||
|
|
on.</p>
|
||
|
|
|
||
|
|
<p>And, as I learned once again in December 1997, you really should
|
||
|
|
keep backups of everything. I only lost a day's work, but it was
|
||
|
|
still annoying, and it could've been much, much worse.</p>
|
||
|
|
|
||
|
|
<h3>A word about the code</h3>
|
||
|
|
|
||
|
|
<p>This code isn't meant to be the ultimate in efficiency or speed,
|
||
|
|
it's intended to be fairly easy to understand and maintain
|
||
|
|
(hopefully). I was also quite keen on having something that was
|
||
|
|
correct, without jumping through a lot of unnecessary hoops.</p>
|
||
|
|
|
||
|
|
<p>If you think this code sucks, don't use it. You're already applying
|
||
|
|
this to your choice of operating system! <tt>:-)</tt></p>

<h2>Versions</h2>

<dl compact>
|
||
|
|
|
||
|
|
<dt><strong>1.1 (April 18, 1998)</strong></dt>
|
||
|
|
<dd>Changes include:
|
||
|
|
<ul>
|
||
|
|
<li>Extract option (<b>x</b>) will preserve a file's mode bits
|
||
|
|
when overwriting an existing file (this may go away if it's
|
||
|
|
not POSIX behaviour).</li>
|
||
|
|
|
||
|
|
<li>Extracted files will now have the proper file type.</li>
|
||
|
|
|
||
|
|
<li>Removed attempt to use <i>umask()</i> to set newly created
|
||
|
|
archive's mode bits; apparently, I'm not sure how it
|
||
|
|
works and my POSIX manual isn't helping.</li>
|
||
|
|
|
||
|
|
<li>Should be 100% endian-neutral now; using this on BeOS for
|
||
|
|
x86 is only useful if you're manipulating <em>PowerPC</em>
|
||
|
|
objects though. The <tt>ar</tt> in
|
||
|
|
<a href="http://www.ninemoons.com/GG/index.html">GeekGadgets</a>
|
||
|
|
should work fine for x86 objects/libraries.</li>
|
||
|
|
|
||
|
|
<li>Updated the <tt>README.txt</tt> file; now it's got useful
|
||
|
|
information about building/using the POSIX ar.</li>

||
