Alright that was a dead end. Here is the source code.
bool CPythonModule::Register()
{
bool bReturn = false;
unsigned int uiSize = static_cast<unsigned
int>(m_LPyMethodDefs.size());
if (m_LPyMethodDefs.size() > 0)
{
m_pEmbMethods = new PyMethodDef[m_LPyMethodDefs.size()+1];
unsigned int uiCounter = 0;
IterQPyMethodDefs iterMethods = m_LPyMethodDefs.begin();
while (m_LPyMethodDefs.end() != iterMethods)
{
m_pEmbMethods[uiCounter].ml_name =
m_LPyMethodDefs.front().sName.c_str();
m_pEmbMethods[uiCounter].ml_meth =
m_LPyMethodDefs.front().pFunction;
m_pEmbMethods[uiCounter].ml_flags = m_LPyMethodDefs.front().iFlags;
m_pEmbMethods[uiCounter].ml_doc =
m_LPyMethodDefs.front().sDoc.c_str();
++uiCounter;
++iterMethods;
}
PyMethodDef PyMethodNullDef = {NULL, NULL, 0, NULL};
m_pEmbMethods[uiSize] = PyMethodNullDef;
Py_InitModule(m_sModuleName.c_str(),m_pEmbMethods);
//PythonInterfaceInst->RegisterModule(this);
m_pInitFunc();
bReturn = true;
}
return bReturn;
}
