<h1>Directory functions</h1>

<p>
OK. First things first. These functions are NOT part of the ANSI standard
library. They may not be supported on your platform.
<p>
Here is a quick summary of each function, they are listed in the order in
which you may want to execute them.
</ul>
<li><b>opendir</b> Open a directory stream.
<li><b>readdir</b> read the current entry in the stream.
<li><b>scandir</b> Find an entry in a direcory.
<li><b>seekdir</b> Jump to a directory offset.
<li><b>telldir</b> Return the current location within the directory stream.
<li><b>rewinddir</b> Return to the start of the directory stream.
<li><b>closedir</b> Close a directory.
</ul>
<hr>
<table bgcolor=ivory>
<tr>
<td>
<pre>
Library: dirent.h
Prototype: DIR *opendir(const char *name);
struct dirent *readdir(DIR *dir);
int scandir(const char *dir, struct dirent ***namelist,
int (*select)(const struct dirent *),
int (*compar)(const void *, const void *));
void seekdir(DIR *dir, off_t offset);
off_t telldir(DIR *dir);
void rewinddir(DIR *dir);
int closedir(DIR *dir);
</pre>
</td>
</tr>

The dirent structure does not seem to be documented in the man pages,
so here it is.

off_t d_off;
