int nng_pipe_close(nng_pipe p);


The nng_pipe_close() function closes the supplied pipe, p. Messages that have been submitted for sending may be flushed or delivered, depending upon the transport and the setting of the NNG_OPT_LINGER option.

Further attempts to use the pipe after this call returns will result in NNG_ECLOSED.

Pipes are automatically closed when their creator closes, or when the remote peer closes the underlying connection.


This function returns 0 on success, and non-zero otherwise.



The pipe p is already closed or was never opened.
