== NAME

nng_stream_free - free byte stream

== SYNOPSIS

[source, c]
----
#include <nng/nng.h>

void nng_stream_free(nng_stream *s);
----

== DESCRIPTION

The `nng_stream_free()` function closes the
xref:nng_stream.5.adoc[byte stream] _s_,
and frees the underlying resources associated with it.

If any operations are pending, such as
xref:nng_stream_send.3str.adoc[`nng_stream_send()`]
or
xref:nng_stream_recv.3str.adoc[`nng_stream_recv()`],
they will be terminated with an `NNG_ECLOSED` error condition.

WARNING: It is important that the application ensure that no further accesses
are made to _s_, as the memory backing it will be reclaimed for other uses.

NOTE: Closing the connection while data is in transmission will likely
lead to loss of that data.
There is no automatic linger or flush to ensure that the socket send buffers
have completely transmitted.

== RETURN VALUES

None.

== ERRORS

None.
