Each character device driver must implement an instance of <code>struct file_operations</code>.
|

That structure defines a call table with the following methods:

<b>Description:</b>

<code>pipe()</code> creates a pair of file descriptors, pointing to a pipe inode, and
|
||||
places them in the array pointed to by <code>filedes</code>.
|
||||
<code>filedes[0]</code> is for reading, <code>filedes[1]</code> is for writing.
|
||||
places them in the array pointed to by <code>fd</code>.
|
||||
<code>fd[0]</code> is for reading, <code>fd[1]</code> is for writing.

<b>Input Parameters:</b>

|

<li><code>filedes[2]</code>. The user provided array in which to catch the pipe file descriptors.</li>
