nng_ctx_close - close context

       The nng_ctx_close() function closes the context ctx. Messages that have been submitted for sending may be
       flushed or delivered, depending upon the transport.

       Further attempts to use the context after this call returns will result in NNG_ECLOSED. Threads waiting
       for operations on the context when this call is executed may also return with an NNG_ECLOSED result.

           Note

           Closing the socket associated with ctx (using nng_close()) also closes this context.

       NNG_ECLOSED
           The context ctx is already closed or was never opened.
