You don't. Or, at least, your question is open to so many different interpretations it's not possible to know what you actually want to do.
Things you may want to do are:
- Read binary data from a file written by a C application
- Pass data from XS back to Perl
- Recreate in Perl a data structure serialised by a C application
- Recreate in Perl a C data structure specified in a .h file
- any number of other possible scenarios I haven't thought of
True laziness is hard work

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
