This function creates a regular file in exactly the same way
as <code class="function">create_proc_entry</code> from <a class="xref" href="ch02.html#regularfile" title="Creating a regular file">the section called “Creating a regular file”</a> does, but also allows to set the read
function <em class="parameter"><code>read_proc</code></em> in one call. This
function can set the <em class="parameter"><code>data</code></em> as well, like
explained in <a class="xref" href="ch03s03.html" title="A single call back for many files">the section called “A single call back for many files”</a>.
