<p>Hi list,</p>
<p> </p>
<p>Has anyone done this before?</p>
<p>I try to pass a gdal dataset as an argument from Python to C.</p>
<p> </p>
<p>in my C code, I have</p>
<p>PyObject* py_my_func(PyObject *self, PyObject *args)<br>
{</p>
<p> PyObject *poDataset;</p>
<p> </p>
<p> if(!PyArg_ParseTuple(args, "Odd", &poDataset, &a1, &a2))<br>
{<br>
return NULL;<br>
}</p>
<p> </p>
<p> my_func(poDataset, a1, a2);<br>
}</p>
<p> </p>
<p>void my_func(GDALDatasetH hDataset, double a1, double a2)</p>
<p>{</p>
<p>}</p>
<p> </p>
<p>Python crashed and hDataset was NULL</p>
<p>Is it possible to do or I did something wrong?</p>
<p> </p>
<p>BTW, I have passed either a filename or a gdal array as an argument from Python to C, with success.</p>
