<a href="https://gitlab.com/TheRealMichaelCatanzaro">Michael Catanzaro</a> created an issue:
</p>
<div></div>
<p dir="auto">The documentation of gnutls_record_send() says:</p>
<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code><span id="LC1" class="line" lang="plaintext">If GNUTLS_E_INTERRUPTED or</span>
<span id="LC2" class="line" lang="plaintext">GNUTLS_E_AGAIN is returned, you must call this function again, with the</span>
<span id="LC3" class="line" lang="plaintext">exact same parameters; alternatively you could provide a NULL pointer</span>
<span id="LC4" class="line" lang="plaintext">for data, and 0 for size. cf. gnutls_record_get_direction().</span></code></pre>
<p dir="auto">But I think this is no longer accurate since gnutls_record_discard_queued() was added. Now you have three choices: call with exact same parameters, call with NULL and 0, or call gnutls_record_discard_queued() and then call gnutls_record_send() with whatever you want. Correct?</p>
<p dir="auto">Proposed revised text:</p>
<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code><span id="LC1" class="line" lang="plaintext">If GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN is returned, you must call this</span>
<span id="LC2" class="line" lang="plaintext">function again with the exact same parameters, or provide a NULL pointer</span>
<span id="LC3" class="line" lang="plaintext">for data and 0 for size, in order to write the same data as before. If you</span>
<span id="LC4" class="line" lang="plaintext">wish to discard the previous data instead of retrying, you must call</span>
<span id="LC5" class="line" lang="plaintext">gnutls_record_discard_queued() before calling gnutls_record_send() with</span>
<span id="LC6" class="line" lang="plaintext">different parameters.</span></code></pre>
