1625/// Since this is a standard library, we do not have the luxury of
1626/// putting initialization code anywhere, because we would not want
1627/// to pay the cost of calling WSAStartup if there ended up being no
1628/// networking. Also, if Zig code is used as a library, Zig is not in
1629/// charge of the start code, and we couldn't put in any initialization
1630/// code even if we wanted to.
1631/// The documentation for WSAStartup mentions that there must be a
1632/// matching WSACleanup call. It is not possible for the Zig Standard
1633/// Library to honor this for the same reason - there is nowhere to put
1634/// deinitialization code.
1635/// So, API users of the zig std lib have two options:
1636/// * (recommended) The simple, cross-platform way: just call `WSASocketW`
1637/// and don't worry about it. Zig will call WSAStartup() in a thread-safe
1638/// manner and never deinitialize networking. This is ideal for an
1639/// application which has the capability to do networking.
1640/// * The getting-your-hands-dirty way: call `WSAStartup()` before doing
1641/// networking, so that the error handling code for WSANOTINITIALISED never
1642/// gets run, which then allows the application or library to call `WSACleanup()`.
1643/// This could make sense for a library, which has init and deinit
1644/// functions for the whole library's lifetime.
