NNG_STREAM(5) NNG Reference Manual NNG_STREAM(5)

NAME

nng_stream - byte stream

SYNOPSIS

#include <nng/nng.h>
typedef struct nng_stream nng_stream;

DESCRIPTION

An nng_stream represents a byte stream. This may correspond to an underlying connection such a TCP connection or a connected UNIX domain socket or named pipe.


Note

The nng_stream object is used for raw byte stream connections, and
should not be confused with a pipe object created on socket using the nng_listen(), nng_dial() or related functions.

These objects are created either establishing an outgoing connection with nng_stream_dialer_dial() or by accepting in incoming connection with nng_stream_listener_accept().

Byte streams are reliable in that data will not be delivered out of order, or with portions missing.

Data can be sent using nng_stream_send() or received with nng_stream_recv().

When the connection is no longer needed, it should be freed with nng_stream_free().


Tip

It is possible to close the connection, without freeing it, by
using nng_stream_close().

Byte streams may, depending on the underlying technology, support various options, which can be accessed using the nng_stream_get() and nng_stream_set() family of functions.
