+== NAME
+
+nng_tcp_send - send to TCP connection
+
+== SYNOPSIS
+
+[source, c]
+----
+#include <nng/nng.h>
+#include <nng/supplemental/tcp/tcp.h>
+
+void nng_tcp_send(nng_tcp *conn, nng_aio *aio);
+----
+
+== DESCRIPTION
+
+The `nng_tcp_send()` function starts an asynchronous send over the
+TCP connection _conn_ from the scatter/gather vector located in the
+asynchronous I/O structure _aio_.
+
+NOTE: The `<<nng_aio_set_iov.3#,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 `<<nng_aio_result.3#,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
+`<<nng_aio_count.3#,nng_aio_count()>>`.
+
+NOTE: While TCP has the notion of urgent (out-of-band) delivery, that is
+used by very few protocols and this API does not support it.
+
+== 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.
