<a name="index-struct-timeval_002c-in-file_002di_002fo-protocol"></a>

<p>The buffer of type <code>struct timeval</code> used by the File-I/O protocol
is defined as follows:
</p>
<div class="smallexample">
<pre class="smallexample">struct timeval {
    time_t tv_sec;  /* second */
    long   tv_usec; /* microsecond */
};
</pre></div>

<p>The integral datatypes conform to the definitions given in the
appropriate section (see <a href="Integral-Datatypes.html#Integral-Datatypes">Integral Datatypes</a>, for details) so this
structure is of size 8 bytes.
</p>
