<p><a name="index-integral-datatypes_002c-in-file_002di_002fo-protocol-3619"></a>
The integral datatypes used in the system calls are <code>int</code>,
<code>unsigned int</code>, <code>long</code>, <code>unsigned long</code>,
<code>mode_t</code>, and <code>time_t</code>.
<p><code>int</code>, <code>unsigned int</code>, <code>mode_t</code> and <code>time_t</code> are
implemented as 32 bit values in this protocol.
<p><code>long</code> and <code>unsigned long</code> are implemented as 64 bit types.
<p>See <a href="Limits.html#Limits">Limits</a>, for corresponding MIN and MAX values (similar to those
in <samp><span class="file">limits.h</span></samp>) to allow range checking on host and target.
<p><code>time_t</code> datatypes are defined as seconds since the Epoch.
<p>All integral datatypes transferred as part of a memory read or write of a
structured datatype e.g. a <code>struct stat</code> have to be given in big endian
byte order.
