-/**
- * \file net_sockets.h
- *
- * \brief   Network sockets abstraction layer to integrate Mbed TLS into a
- *          BSD-style sockets API.
- *
- *          The network sockets module provides an example integration of the
- *          Mbed TLS library into a BSD sockets implementation. The module is
- *          intended to be an example of how Mbed TLS can be integrated into a
- *          networking stack, as well as to be Mbed TLS's network integration
- *          for its supported platforms.
- *
- *          The module is intended only to be used with the Mbed TLS library and
- *          is not intended to be used by third party application software
- *          directly.
- *
- *          The supported platforms are as follows:
- *              * Microsoft Windows and Windows CE
- *              * POSIX/Unix platforms including Linux, OS X
