Returns the current status of a socket.
sock_status() function retrieves the current status of a socket identified by the file descriptor
sock and stores the status in the
ret_status memory location.
;;; Returns the current status of a socket (@interface func (export "sock_status") (param $fd $fd) (result $error (expected $sock_status (error $errno))) )
ctx: A mutable reference to the function environment.
sock: The file descriptor of the socket whose status will be retrieved.
ret_status: A WebAssembly pointer to a memory location where the status of the socket will be stored.
The function returns an
Errno value indicating the outcome of the operation. If the operation is successful,
Errno::Success is returned. If an error occurs, an appropriate
Errno value is returned.

- The status of the socket is stored in the
ret_statusmemory location, which should be a
WasmPtr<Sockstatus>pointing to a writable memory region.
- The possible socket status values are:
Opening: The socket is in the process of opening.
Opened: The socket has been successfully opened.
Closed: The socket has been closed.
Failed: An error occurred while opening or using the socket.
- The behavior and limitations of the
sock_status()function may vary depending on the specific runtime environment and underlying networking implementation. It is important to consult the documentation or specifications of the specific environment to understand its behavior in that context.
