80 A value representing the content length in bytes if the length
81 is known (this can include a zero length). Otherwise, the value
82 will be <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">none</span></code>.
89 <code class="computeroutput"><span class="identifier">ec</span></code>
94 An output parameter which the function may set to indicate an
