Cast void pointer to C struct pointer and access its members?

Hi,

I have TestCast.i:

%module test_cast

%{
#include "TestCast.hpp"
%}

%include <stdint.i>

%include "TestCast.hpp"
%template(convert_foo) convert<Foo*>;
%template(convert_bar) convert<Bar*>;



and TestCast.hpp:

#include <cstdint>
#include <iostream>

#pragma pack(1)
struct Foo {
uint8_t a;
char b;
int32_t c;
};
#pragma pack()

void* get_foo() {
static Foo foo{1, 'b', 65535};
return static_cast<void*>(&foo);
}

template <typename T>
T* convert(void* data) noexcept {
return static_cast<T*>(data);
}

I managed to cast the void pointer returned by get_foo() to Foo**:
>>> import test_cast
>>> foo_void_ptr = test_cast.get_foo()
>>> print(foo_void_ptr)
<Swig Object of type 'void *' at 0x7f9613abd990>
>>> foo_ptr = test_cast.convert_foo(foo_void_ptr)
>>> print(foo_ptr)
<Swig Object of type 'Foo **' at 0x7f9613af3f00>

Questions:
1.  How can I get Foo* instead of Foo**?
2.  How can I access the member in Foo in python?
3.  Is there a more elegant way to cast void* into C struct?

Thanks!
