<BODY>
Cleanup of the timeout and Fl::wait() code. This one calls the clock function less than half as much, which resulted in a noticable improvement in a flip book program I was working on. The code looks nicer, too, and I am reasonably certain it works the same. Fl::wait(time) with a time greater than the system can handle (24.855 days on NT, the same on some Unix systems) will now act as though the time is infinity. Before it would do unpredictable things. "USE_POLL" now compiles and works, although it is disabled by default. poll() is an alternative to the Unix select() call which is available on Linux and Irix, but I don't know if it is faster, you can try it by editing config.h. I tried making the NT USE_ASYNC_SELECT code do translate/dispatch of the select events on the assumption (based on experience) that not doing this to every event gives NT fits. This appears to work but I'm not sure if it fixes anything. X version does not crash if Fl::wait() is called when the display is closed (it will not return unless you have a timeout or fd callback set up, though). Fixed up the documentation for all of this, including getting rid of some completely misleading documentation. Now I need to get this stuff into 2.0... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.0@1215 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

<P>FLTK provides a &quot;tab completion&quot; file chooser that
makes it easy to choose files from large directories. This file
chooser has several unique features, the major one being that
the Tab key completes filenames like it does in Emacs or tcsh,
and the list always shows all possible completions.

Cleanup of the timeout and Fl::wait() code. This one calls the clock function less than half as much, which resulted in a noticable improvement in a flip book program I was working on. The code looks nicer, too, and I am reasonably certain it works the same. Fl::wait(time) with a time greater than the system can handle (24.855 days on NT, the same on some Unix systems) will now act as though the time is infinity. Before it would do unpredictable things. "USE_POLL" now compiles and works, although it is disabled by default. poll() is an alternative to the Unix select() call which is available on Linux and Irix, but I don't know if it is faster, you can try it by editing config.h. I tried making the NT USE_ASYNC_SELECT code do translate/dispatch of the select events on the assumption (based on experience) that not doing this to every event gives NT fits. This appears to work but I'm not sure if it fixes anything. X version does not crash if Fl::wait() is called when the display is closed (it will not return unless you have a timeout or fd callback set up, though). Fixed up the documentation for all of this, including getting rid of some completely misleading documentation.

<H3>Description</H3>
<P>This is a portable and const-correct wrapper for the
<tt>scandir()</tt> function. <tt>d</tt> is the name of a
directory; it does not matter if it has a trailing slash or not.
For each file in that directory a &quot;dirent&quot; structure
is created. The only portable thing about a dirent is that
<TT>dirent.d_name</TT> is the <TT>nul</TT>-terminated file name.
An array of pointers to these <TT>dirent</TT>'s is created and a
pointer to the array is returned in <tt>*list</tt>. The number
of entries is given as a return value. If there is an error
reading the directory a number less than zero is returned, and
<tt>errno</tt> has the reason; <tt>errno</tt> does not work
under WIN32. The files are sorted in &quot;alphanumeric&quot;
order, where an attempt is made to put unpadded numbers in
consecutive order.
<P>You can free the returned list of files with the following
code:

for (int i = return_value; i &gt; 0;) {
