[RFC] Ctypes III: Implementation

[darleybarreto]

This is the #3 (third) tracking issue w.r.t the implementation of _ctypes. The main goal is to track the implementation progress based on the discussion in #2 .

[darleybarreto]

Ideal implementation road map:

• [ ] Implement PySimple (Cpython's Simple_Type/PyCSimpleType_Type equivalent)

• [ ] Implement PyCFuncPtr (Cpython's PyCFuncPtr_Type/PyCFuncPtrType_Type equivalent)

• [ ] Implement PyCArray (Cpython's PyCArray_Type/PyCArrayType_Type equivalent)

• [ ] Implement PyCStruct (Cpython's Struct_Type/PyCStructType_Type equivalent)

• [ ] Implement PyCUnion (Cpython's Union_Type/UnionType_Type equivalent)

• [ ] Implement PyCPointer (Cpython's PyCPointer_Type/PyCPointerType_Type equivalent)

• [ ] Implement helper functions

  • [ ] sizeof(cdata)
  • [ ] sizeof(ctype)
  • [ ] byref(cdata)
  • [ ] addressof(cdata)
  • [ ] pointer(cdata)
  • [ ] bytes(cdata)
  • [ ] dlsym
  • [ ] dlopen
  • [ ] dlclose

• [ ] Memory functions addresses

  • [ ] memmove
  • [ ] memset
  • [ ] string_at
  • [ ] cast
  • [ ] wstring_at
