Storing unsafe C derivative of temporary Python reference

To store an unsafe C derivative of a temporary Python reference, you can use the `Py_INCREF()` function to increment the reference count and prevent the object from being deallocated while you still need it in C. Here's an example:
```c
#include <Python.h>
PyObject* my_c_object = NULL;
PyObject* get_temp_python_object() {
PyObject* temp_object = ... // obtain the temporary Python object
Py_INCREF(temp_object); // increment the reference count
my_c_object = temp_object; // store the reference in a global variable
return temp_object;
}
void release_python_object() {
Py_XDECREF(my_c_object); // decrement the reference count
my_c_object = NULL; // reset the global variable
}
int main() {
// Use the temporary Python object in C
PyObject* temp_object = get_temp_python_object();
// ...
release_python_object();
// Continue with other operations
return 0;
}
```
Make sure to call `release_python_object()` when you no longer need the C derivative of the temporary Python reference to avoid memory leaks.
