I-m new to pyrex and I&#39;m trying to use it to have access to a library<br>
(MesaSR, <a href="http://www.mesa-imaging.ch/drivers.php" target="_blank">http://www.mesa-imaging.ch/drivers.php</a>), but I can&#39;t make use of<br>
pointers.<br>
<br>
I can&#39;t seem to define a function that one of its arguments it&#39;s a pointer<br>
(a function that initialize the structure). I&#39;m also having troubles with<br>
using the SR_GetImage that returns a void* pointer.<br>
<br>
My code is as follows:<br>
<br>
import numpy<br>
<br>
cdef extern from &quot;libMesaSR.h&quot;:<br>
    ctypedef SRCAM<br>
