The functions described in this page allow an application to asynchronously wait
  for touch on a FIDO2 authenticator. This is useful when multiple
  authenticators are present and the application needs to know which one to use.
<p class="Pp">The <code class="Fn">fido_dev_get_touch_begin</code>() function
    initiates a touch request on <var class="Fa">dev</var>.</p>
<p class="Pp">The <code class="Fn">fido_dev_get_touch_status</code>() function
    continues an ongoing touch request on <var class="Fa">dev</var>, blocking up
    to <var class="Fa">ms</var> milliseconds. On success,
    <var class="Fa">touched</var> will be updated to reflect the touch request
    status. If <var class="Fa">touched</var> is 1, the device was touched, and
    the touch request is terminated. If <var class="Fa">touched</var> is 0, the
    application may call <code class="Fn">fido_dev_get_touch_status</code>() to
    continue the touch request, or <code class="Fn">fido_dev_cancel</code>() to
    terminate it.</p>

The error codes returned by <code class="Fn">fido_dev_get_touch_begin</code>()
  and <code class="Fn">fido_dev_get_touch_status</code>() are defined in
  <code class="In">&lt;<a class="In">fido/err.h</a>&gt;</code>. On success,
  <code class="Dv">FIDO_OK</code> is returned.

The <code class="Fn">fido_dev_get_touch_status</code>() function will cause a
  command to be transmitted to U2F authenticators. These transmissions should
  not exceed a frequency of 5Hz.
