CONFIG_NET_SOCKETS_POSIX_NAMES

POSIX names for Sockets API (without full POSIX API)

Type: bool

Help

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.
