== NAME

nng_stream_dialer_dial - initiate outgoing byte stream connection

== SYNOPSIS

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

void nng_stream_dialer_dial(nng_stream_dialer *d, nng_aio *aio);
----

== DESCRIPTION

The `nng_stream_dialer_dial()` attempts to establish a connection to the
remote peer for the dialer _d_.
The operation is completed asynchronously, using _aio_.

TIP: The peer address is determined by the address specified using
xref:nng_stream_dialer_alloc.3str.adoc[`nng_stream_dialer_alloc()`] or 
xref:nng_stream_dialer_alloc_url.3str.adoc[`nng_stream_dialer_alloc_url()`]. 

If a connection is successfully established, the _aio_ will have the
resulting
xref:nng_stream.5.adoc[`nng_stream`] object stored as its first output.
(See
xref:nng_aio_get_output.3.adoc[`nng_aio_get_output()`].)

== RETURN VALUES

None.

== ERRORS

[horizontal]
`NNG_EADDRINVAL`:: The address specified is invalid.
`NNG_ECANCELED`:: The operation was aborted.
`NNG_ECLOSED`:: The dialer is closed.
`NNG_ECONNREFUSED`:: The connection was refused by the server.
`NNG_ECONNRESET`:: The connection was reset by the server.
`NNG_ENOMEM`:: Insufficient free memory exists.
