The <code class="Fn">fido_dev_set_pin</code>() function sets the PIN of device
<var class="Fa">dev</var> to <var class="Fa">pin</var>, where
<var class="Fa">pin</var> is a NUL-terminated UTF-8 string. If
<var class="Fa">oldpin</var> is not NULL, the device's PIN is changed from
<var class="Fa">oldpin</var> to <var class="Fa">pin</var>, where
<var class="Fa">pin</var> and <var class="Fa">oldpin</var> are NUL-terminated
UTF-8 strings.
<p class="Pp">The <code class="Fn">fido_dev_get_retry_count</code>() function
fills <var class="Fa">retries</var> with the number of PIN retries left in
<var class="Fa">dev</var> before lock-out, where
<var class="Fa">retries</var> is an addressable pointer.</p>
<p class="Pp">The <code class="Fn">fido_dev_get_uv_retry_count</code>() function
fills <var class="Fa">retries</var> with the number of built-in UV retries
left in <var class="Fa">dev</var> before built-in UV is disabled, where
<var class="Fa">retries</var> is an addressable pointer.</p>
<p class="Pp">The <code class="Fn">fido_dev_reset</code>() function performs a
reset on <var class="Fa">dev</var>, resetting the device's PIN and erasing
credentials stored on the device.</p>
<p class="Pp">Please note that <code class="Fn">fido_dev_set_pin</code>(),
<code class="Fn">fido_dev_get_retry_count</code>(),
<code class="Fn">fido_dev_get_uv_retry_count</code>(), and
<code class="Fn">fido_dev_reset</code>() are synchronous and will block if

The error codes returned by <code class="Fn">fido_dev_set_pin</code>(),
<code class="Fn">fido_dev_get_retry_count</code>(),
<code class="Fn">fido_dev_get_uv_retry_count</code>(), and
<code class="Fn">fido_dev_reset</code>() are defined in
<code class="In"><<a class="In">fido/err.h</a>></code>. On success,
<code class="Dv">FIDO_OK</code> is returned.

Regarding <code class="Fn">fido_dev_reset</code>(), the actual user-flow to
perform a reset is outside the scope of the FIDO2 specification, and may
therefore vary depending on the authenticator. Yubico authenticators will
return <code class="Dv">FIDO_ERR_NOT_ALLOWED</code> if a reset is issued later
than 5 seconds after power-up, and
<code class="Dv">FIDO_ERR_ACTION_TIMEOUT</code> if the user fails to confirm
the reset by touching the key within 30 seconds.
