# libpEpDatatypes – A C++ wrapper for the basic C datatypes defined by the pEpEngine.

## Design goals & principles

* implement move c'tor & operator for cheep moves
* _Qpen question_: deep copy / shallow copy (with ref couning?) / only explicit copy?
* always initialize all members. Better safe than sorry.
* Ownership of the member pointees: rule of thumb: "const" pointees are non-owned, non-const pointees are owned by the data structure. Exceptional cases are documented explicitly.

## Public API
* defined in `namespace pEp` – Beware: it is shared with libpEpAdapter!)
* header files are installed in `PREFIX/include/pEp/` and are used via `#include <pEp/filename.hh>` – (Also shared with libpEpAdapter!)
* the linked list datatypes implement the API of [`std::forward_list`](https://en.cppreference.com/w/cpp/container/forward_list)

## Implementation details
* internal stuff is in `namespace pEp::datatypes`
