Using <i>nxdir,</i> I get a SEGV:<br>
<br>
<blockquote>nxdir -t multi mcstas.h5 -p "*" --data-mode script<br>
*** stack smashing detected ***: nxdir terminated<br>
Segmentation fault<br>
</blockquote>
<br>
System is:<br>
<blockquote>NeXus 4.2.0 (from tarball)<br>
Linux Ubuntu 8.04 64 bits<br>
</blockquote>
<br>
Generation of NeXus file with McStas performs OK (file attached),
except for warning messages when trying to create/open already
existing/opened groups/objects. <br>
<br>
The only way to seemingly test if a group exists without creating with
an error message is to call <i>NXgetgroupinfo</i> to get the current
group and make a strcmp with the requested group.<br>
<br>
There is unfortunately no such routine for data sets. We can not obtain
the current Data Set name, only its dimension, rank and type with <i>NXgetinfo.<br>
<br>
</i>An other solution suggested by Mark K is to unactivate HDF error
messages with <i>NXMDisableErrorReporting();</i> and reset it with <i>NXMEnableErrorReporting();<br>
<br>
</i>If you think of a better way to inquire groups/data sets, and a
solution for nxdir that fails showing data values/attributes, please
tell me.<br>
