| <p>The <code class="docutils literal notranslate"><span class="pre">get_schema</span></code> and <code class="docutils literal notranslate"><span class="pre">get_next</span></code> callbacks may return an error under the form |
| of a non-zero integer code. Such error codes should be interpreted like |
| <code class="docutils literal notranslate"><span class="pre">errno</span></code> numbers (as defined by the local platform). Note that the symbolic |
| forms of these constants are stable from platform to platform, but their numeric |
| values are platform-specific.</p> |
| <p>In particular, it is recommended to recognize the following values:</p> |
| <ul class="simple"> |
| <li><p><code class="docutils literal notranslate"><span class="pre">EINVAL</span></code>: for a parameter or input validation error</p></li> |
| <li><p><code class="docutils literal notranslate"><span class="pre">ENOMEM</span></code>: for a memory allocation failure (out of memory)</p></li> |
| <li><p><code class="docutils literal notranslate"><span class="pre">EIO</span></code>: for a generic input/output error</p></li> |
