*POSIX names for Sockets API (without full POSIX API)*

Type: ``bool``

Help

.. code-block:: none

    With this option, Socket API functions are available under the
    standard POSIX names like socket(), recv(), and close(), etc.,
    even if full POSIX API (CONFIG_POSIX_API) is not enabled. (Note
    that close() may require a special attention, as in POSIX it
    closes any file descriptor, while with this option enabled, it
    will apply only to sockets.)

    Various networking libraries require either
    CONFIG_NET_SOCKETS_POSIX_NAMES or CONFIG_POSIX_API to be set.
    If both are disabled, Zephyr's socket functions will be
    available (only) with ``zsock_`` prefix, (e.g. `zsock_socket`).
    This is useful only in peculiar cases, e.g. when integrating
    with 3rd-party socket libraries.
