<div>Hello, </div>
<div><br>
</div>
<div>I'm having difficulties translating linked list from given c++ API to python.</div>
<div><br>
</div>
<div>I have a struct (DataType) holding some data (const unsigned char* data) and the size of this data. Then I have a struct ListNode that has a void* data, that should point to a DataTypeObj.</div>
<div><br>
</div>
<div>Where I'm stuck:</div>
<div>DataType and ListNode can be translated with SIP, but I suspect something goes wrong when passing the address of dataTypeObj to listNodeObj.data.</div>
<div>The address of dataTypeObj in hex format is the address the debugger shows me, therefore the ID should be right.</div>
<div>But the content is not. dataTypeObj.size accessed from listNodeObj is garbage.</div>
<div><br>
</div>
<div>This is my header file:</div>
