## nng_stream_dialer_dial

Initiate outgoing byte stream connection.

### Synopsis

```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.adoc[`nng_stream_dialer_alloc`] or xref:nng_stream_dialer_alloc.adoc[`nng_stream_dialer_alloc_url`].

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

### 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.
