<p>Dear GDAL devs,<br></p><p>I am using GDAL 3.8.4 and have some tests in a Rust codebase that 
check behavior on trying to open non-existing NetCDF files, non-existing 
groups within the NetCDF, etc.</p>
<p>I am working with the dataset by opening it as a multidimensional GDAL dataset and then use <code>GDALGroupOpenGroup</code>, etc.</p>
<p>The testing works fine, but I am getting loads of diagnostic messages from the underlying NetCDF library.</p>

<p>How can I mute these <code>HDF5-DIAG</code> messages?</p>
<p>I tried sending GDAL's error logging to /dev/null but this does not change anything.</p><p><br></p><p>Best regards<br></p><p> Christian<br></p>
