:ref:`LuaSocket wrapper functions <socket-luasocket>`
Several methods for emulating the LuaSocket API
Typically a socket session will begin with the setup functions, will set one or more flags, will have a loop with sending and receiving functions, will end with the teardown functions -- as an example at the end of this section will show. Throughout, there may be error-checking and waiting functions for synchronization. To prevent a fiber containing socket functions from "blocking" other fibers, the :ref:`implicit yield rules <app-implicit-yields>` will cause a yield so that other processes may take over, as is the norm for :ref:`cooperative multitasking <app-cooperative_multitasking>`.
For all examples in this section the socket name will be sock and the function invocations will look like ``sock:function_name(...)``.
Create a new TCP or UDP socket. The argument values are the same as in the `Linux socket(2) man page <http://man7.org/linux/man-pages/man2/socket.2.html>`_.
