## nng_stream_close

Close byte stream.

### Synopsis

```c
#include <nng/nng.h>

void nng_stream_close(nng_stream *s);
```

### Description

The `nng_stream_close` function closes the byte stream _s_.

Any pending operations, as well as any further new operations, will fail with an `NNG_ECLOSED` error.

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.

NOTE: Closing the connection does not free the resources associated with it.
Once it is certain that no more operations are pending on the connection, it should be freed with xref:nng_stream_free.adoc[`nng_stream_free`].
