+== NAME
+
+nng_stream_send - send to byte stream
+
+== SYNOPSIS
+
+[source, c]
+----
+#include <nng/nng.h>
+
+void nng_stream_send(nng_stream *s, nng_aio *aio);
+----
+
+== DESCRIPTION
+
+The `nng_stream_send()` function starts an asynchronous send over the
+xref:nng_stream.5.adoc[byte stream] _s_
+from the scatter/gather vector located in the
+asynchronous I/O structure _aio_.
+
+NOTE: The
+xref:nng_aio_set_iov.3.adoc[`nng_aio_set_iov()`]
+function must have been
+called first, to set the scatter/gather vector for _aio_.
+
+This function returns immediately, with no return value.
+Completion of the operation is signaled via the _aio_, and the final
+result may be obtained via
+xref:nng_aio_result.3.adoc[`nng_aio_result()`].
+That result will either be zero or an error code.
+
+The I/O operation completes as soon as at least one byte has been
+sent, or an error has occurred.
+Therefore, the number of bytes sent may be less than requested.
+The actual number of bytes sent can be determined with
+xref:nng_aio_count.3.adoc[`nng_aio_count()`].
+
+== RETURN VALUES
+
+None.
+
+== ERRORS
+
+[horizontal]
+`NNG_ECANCELED`:: The operation was canceled.
+`NNG_ECLOSED`:: The connection was closed.
+`NNG_ECONNRESET`:: The peer closed the connection.
+`NNG_EINVAL`:: The _aio_ does not contain a valid scatter/gather vector.
+`NNG_ENOMEM`:: Insufficient free memory to perform the operation.
+`NNG_ETIMEDOUT`:: Timeout waiting for data from the connection.
