<h2>Notes<a class="headerlink" href="#notes" title="Link to this heading">#</a></h2>
<p>Virtually all PETSc functions return an error code. It is the callers responsibility to check
the value of the returned error code after each PETSc call to determine if any errors
occurred. A set of convenience macros (e.g. <code class="docutils notranslate"><span class="pre"><a href="../../manualpages/Sys/PetscCall.html">PetscCall</a>()</span></code>, <code class="docutils notranslate"><span class="pre"><a href="../../manualpages/Sys/PetscCallVoid.html">PetscCallVoid</a>()</span></code>) are provided
for this purpose. Failing to properly check for errors is not supported, as errors may leave
PETSc in an undetermined state.</p>
<p>One can retrieve the error string corresponding to a particular error code using
<code class="docutils notranslate"><span class="pre"><a href="../../manualpages/Sys/PetscErrorMessage.html">PetscErrorMessage</a>()</span></code>.</p>
<p>The user can also configure PETSc with the <code class="docutils notranslate"><span class="pre">--with-strict-petscerrorcode</span></code> option to enable
compiler warnings when the returned error codes are not captured and checked. Users are
<em>heavily</em> encouraged to opt-in to this option, as it will become enabled by default in a
future release.</p>
