+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`].

+typedef struct nng_stream_dialer nng_stream_dialer;
+```
+
+### Description
+
+(((byte stream, dialer)))
+An `nng_stream_dialer` is a handle to a dialer for byte streams, and is responsible for creating `nng_stream` objects (corresponding to connected byte streams) by connecting to remote peers.
+
+NOTE: The `nng_stream_dialer` object is used for low-level byte stream connections, and should not be confused with a high-level xref:../dialer/index.adoc[`nng_dialer`] object.

+
+Allocate byte stream dialer.
+
+### Synopsis
+
+```c
+#include <nng/nng.h>
+
+int nng_stream_dialer_alloc(nng_stream_dialer **dp, const char *addr);
+
+int nng_stream_dialer_alloc_url(nng_stream_dialer **dp, const nng_url *url);
+```
+
+### Description
+
+These functions allocates a dialer for byte streams.
+Dialers create byte stream objects by initiating outgoing connections, via the xref:nng_stream_dialer_dial.adoc[`nng_stream_dialer_dial`] function.
+
+The first form, `nng_stream_dialer_alloc`, connects to the address specified by _addr_, which should be a string representing a URL.
+
+The second form, `nng_stream_dialer_alloc_url`, takes a pre-parsed or pre-constructed
+xref:../util/nng_url.adoc[`nng_url`] object to determine the remote address.
+
+These functions may support different URL schemes, such as `ipc://`, `tcp://`, `tls+tcp://`, or `ws://`.
+
+Both forms store the dialer in the location referenced by _dp_.
+
+### Return Values
+
+These functions return 0 on success, and non-zero otherwise.
+
+### Errors
+
+[horizontal]
+`NNG_ENOMEM`:: Insufficient free memory exists.
+`NNG_ENOTSUP`:: The URL scheme is not supported by the implementation.
+`NNG_EADDRINVAL`:: The URL requested is invalid.

+```
+
+### Description
+
+
+The `nng_stream_dialer_get` functions are used to retrieve option values for the
+xref:nng_stream_dialer.adoc[byte stream dialer] _d_.
+
+The actual options that may be retrieved in this way vary.
+A number of them are documented in xref:../options/index.adoc[Options] and additional linked documents.
+
+#### Forms
+
+In all of these forms, the option _opt_ is retrieved from the byte stream dialer _d_.
+The forms vary based on the type of the option they take.
+
+The details of the type, size, and semantics of the option will depend
+on the actual option, and will be documented with the option itself.
+
+TIP: It may be easier to use one of the typed forms of this function.
+
+`nng_stream_dialer_get`::
+This function is untyped and can be used to retrieve the value of any option.
+The caller must store a pointer to a buffer to receive the value in _val_,
+and the size of the buffer shall be stored at the location referenced by
+_sizep_.
++
+When the function returns, the actual size of the data copied (or that
+would have been copied if sufficient space were present) is stored at
+the location referenced by _sizep_.
+If the caller's buffer is not large enough to hold the entire object,
+then the copy is truncated.
+Therefore the caller should check for truncation by verifying that the
+returned size in _sizep_ does not exceed the original buffer size.
++
+It is acceptable to pass `NULL` for _val_ if the value in _sizep_ is zero.
+This can be used to determine the size of the buffer needed to receive
+the object.
+
+`nng_stream_dialer_get_bool`::
+This function is for options which take a Boolean (`bool`).
+
+`nng_stream_dialer_get_int`::
+This function is for options which take an integer (`int`).
+
+`nng_stream_dialer_get_ms`::
+This function is used to retrieve time durations, stored as a number of milliseconds.
+(The special value ((`NNG_DURATION_INFINITE`)) means an infinite amount of time, and
+the special value ((`NNG_DURATION_DEFAULT`)) means a context-specific default.)
+
+`nng_stream_dialer_get_ptr`::
+This function is used to retrieve a pointer to structured data.
+The data referenced is generally managed using other functions.
+Note that this form is somewhat special in that the object is generally
+not copied, but instead the *pointer* to the object is copied.
++
+NOTE: Care must be taken to ensure that the application respects any
+considerations about the lifetime of the underlying object.
+See the documentation for the option for more specific guidance.
+
+`nng_stream_dialer_get_size`::
+This function is used to retrieve a size,
+typically for buffer sizes, message maximum sizes, and similar options.
+
+`nng_stream_dialer_get_addr`::
+This function is used to retrieve a
+xref:../opts/nng_sockaddr.adoc[socket address].
+
+`nng_stream_dialer_get_string`::
+This function is used to retrieve a `NUL`-terminated string.
+This string is created from the source using xref:../util/nng_strdup.adoc[`nng_strdup`].
+Consequently, it must be freed by the caller using xref:../util/nng_strfree.adoc[`nng_strfree`] when it is no longer needed.
+
+`nng_stream_dialer_get_uint64`::
+This function is used to retrieve a 64-bit unsigned value.
+This is typically used for identifiers, network numbers, and similar options.
+
+### Return Values
+
+These functions return 0 on success, and non-zero otherwise.
+
+### Errors
+
+[horizontal]
+`NNG_ECLOSED`:: The dialer is closed.
+`NNG_EINVAL`:: There was insufficient space to receive the object.
+ The amount of data actually needed is returned in _sizep_.
+`NNG_ENOTSUP`:: The option is not supported.
+`NNG_EWRITEONLY`:: The option may not read.

+
+### Description
+
+The `nng_stream_dialer_set` functions are used to configure options for the byte stream dialer _d_.
+The actual options that may be configured in this way vary, and are specified by _opt_.
+A number of them are documented in xref:../opts/index.adoc[Options].
+
+Additionally some transport-specific options are documented with the transports.
+
+TIP: It may be easier to use one of the typed forms of this function.
+
+#### Forms
+
+The details of the type, size, and semantics of the option will depend on the actual option, and will be documented with the option itself.
+
+`nng_stream_dialer_set`::
+This function is untyped, and can be used to configure any arbitrary data.
+The _val_ pointer addresses the data to copy, and _size_ is the
+size of the objected located at _val_.
+
+`nng_stream_dialer_set_bool`::
+This function is for options which take a Boolean (`bool`).
+
+`nng_stream_dialer_set_int`::
+This function is for options which take an integer (`int`).
+
+`nng_stream_dialer_set_ms`::
+This function is used to configure time durations (such as timeouts) using the type xref:nng_duration.adoc[`nng_duration`].
+The duration is an integer number of milliseconds.
+
+`nng_stream_dialer_set_ptr`::
+This function is used to pass a pointer to structured data.
+The data referenced by is generally managed by other functions.
++
+NOTE: This form is somewhat special in that the object is generally not copied, but instead the *pointer* to the object is copied.
+Please see the documentation for the specific option for further details.
+
+`nng_stream_dialer_set_size`::
+This function is used to set a size option.
+
+`nng_stream_dialer_set_string`::
+This function is used to set a string option.
+Strings passed this way must be legal UTF-8 strings, terminated with a `NUL` (`\0`) byte.
+
+`nng_stream_dialer_set_uint64`::
+This function is used to configure a 64-bit unsigned value/
+This is typically used for identifiers, network numbers,
+and similar options.
+
+`nng_stream_dialer_set_addr`::
+This function is used to configure a xref:../opts/nng_sockaddr.adoc[socket address].
+The value is copied, and thus the caller may discard the supplied value immediately after this function returns.
+
+### Return Values
+
+This function returns 0 on success, and non-zero otherwise.
+
+### Errors
+
+[horizontal]
+`NNG_ECLOSED`:: The dialer is closed.
+`NNG_EINVAL`:: Either _data_ or _size_ are invalid.
+`NNG_ENOTSUP`:: The option is not supported.

+
+int nng_stream_listener_alloc_url(nng_stream_listener **lp, const nng_url *url);
+```
+
+### Description
+
+These functions allocates a listener for byte streams.
+Listeners create `nng_stream` objects by accepting incoming connections, via the xref:nng_stream_listener_accept.adoc[`nng_stream_listener_accept`] function.
+
+The first form, `nng_stream_listener_alloc`, connects to the address specified by _addr_, which should be a string representing a URL.
+
+The second form, `nng_stream_listener_alloc_url`, takes a pre-parsed or pre-constructed xref:../opts/nng_url.adoc[`nng_url`] object to determine the remote address.
+
+These functions may support different URL schemes, such as `ipc://`, `tcp://`, `tls+tcp://`, or `ws://`.
+
+Both forms store the listener in the location referenced by _lp_.
+
+### Return Values
+
+These functions return 0 on success, and non-zero otherwise.
+
+### Errors
+
+[horizontal]
+`NNG_ENOMEM`:: Insufficient free memory exists.
+`NNG_ENOTSUP`:: The URL scheme is not supported by the implementation.

+
+#### Forms
+
+In all of these forms, the option _opt_ is retrieved from the byte stream listener _l_.
+The forms vary based on the type of the option they take.
+
+The details of the type, size, and semantics of the option will depend on the actual option, and will be documented with the option itself.
+
+TIP: It may be easier to use one of the typed forms of this function.
+
+`nng_stream_listener_get`::
+This function is untyped and can be used to retrieve the value of any option.
+The caller must store a pointer to a buffer to receive the value in _val_, and the size of the buffer shall be stored at the location referenced by _sizep_.

++
+It is acceptable to pass `NULL` for _val_ if the value in _sizep_ is zero.
+This can be used to determine the size of the buffer needed to receive the object.
+

+This function is for options which take a Boolean (`bool`).
+
+`nng_stream_listener_get_int`::
+This function is for options which take an integer (`int`).
+
+`nng_stream_listener_get_ms`::
+This function is used to retrieve time durations (`nng_duration`) stored as a number of milliseconds.
+(The special value ((`NNG_DURATION_INFINITE`)) means an infinite amount of time, and the special value ((`NNG_DURATION_DEFAULT`)) means a context-specific default.)

+The data referenced is generally managed using other functions.
+Note that this form is somewhat special in that the object is generally not copied, but instead the *pointer* to the object is copied.
++
+Care must be taken to ensure that the application respects any considerations about the lifetime of the underyling object.
+See the documentation for the option for more specific guidance.
+
+`nng_stream_listener_get_size`::
+This function is used to retrieve a size,
+typically for buffer sizes, message maximum sizes, and similar options.
+
+`nng_stream_listener_get_addr`::
+This function is used to retrieve a xref:../opts/nng_sockaddr.adoc[socket address].
+

+This function is used to retrieve a `NULL`-terminated string.
+This string is created from the source using xref:../util/nng_strdup.adoc[`nng_strdup`].

+### Synopsis
+
+```c
+#include <nng/nng.h>
+
+int nng_stream_listener_listen(nng_stream_listener *l);
+```
+
+### Description
+
+The `nng_stream_listener_listen` attempts to bind the listener _l_ to the local address specified when the listener was created.
+
+This must generally be done before accepting incoming connections using xref:nng_stream_listener_accept.adoc[`nng_stream_listener_accept`].
+
+For some transports this will also perform other actions.
+For example, with TCP listeners it will configure the underlying port into passive mode, ready to accept an incoming connection, and established a listen queue for receiving incoming connections.
+
+If binding the listener requires allocation of an address (for example when a TCP port number of zero is specified, indicating that an ephemeral port should be used), this operation will allocate that resource.
+This can permit retrieval of the selected address using
+xref:nng_stream_listener_get.adoc[`nng_stream_listener_get`], typically with the `NNG_OPT_LOCADDR` option.
+
+### Return Values
+
+This function returns 0 on success, and non-zero otherwise.
+
+### Errors
+
+[horizontal]

+
+### Description
+
+The `nng_stream_listener_set` functions are used to configure options for the byte stream listener _l_.
+The actual options that may be configured in this way vary, and are specified by _opt_.
+A number of them are documented in ../opts/index.adoc[Options].

+
+NOTE: The xref:../aio/nng_aio_set_iov.adoc[`nng_aio_set_iov`] function must have been called first, to set the scatter/gather vector for _aio_.

+NOTE: The xref:../aio/nng_aio_set_iov.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:../aio/nng_aio_result.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:../aio/nng_aio_count.adoc[`nng_aio_count`].
+
+### 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.

+## nng_stream_set
+
+Set option on byte stream.
+
+### Synopsis
+
+```c
+#include <nng/nng.h>
+
+int nng_stream_set(nng_stream *s, const char *name, const void *data, size_t size);
+
+int nng_stream_set_bool(nng_stream *s, const char *opt, bool val);
+int nng_stream_set_int(nng_stream *s, const char *opt, int val);
+int nng_stream_set_ms(nng_stream *s, const char *opt, nng_duration val);
+int nng_stream_set_ptr(nng_stream *s, const char *opt, void *val);
+int nng_stream_set_size(nng_stream *s, const char *opt, size_t val);
+int nng_stream_set_string(nng_stream *s, const char *opt, const char *val);
+int nng_stream_set_uint64(nng_stream *s, const char *opt, uint64_t val);
+int nng_stream_set_addr(nng_stream *s, const char *opt, const nng_sockaddr *val);
+```
+
+### Description
+
+The `nng_stream_set` functions are used to configure options for the byte stream _s_.
+The actual options that may be configured in this way vary, and are specified by _opt_.
+A number of them are documented in xref:../opts/index.adoc[Options].
+
+#### Forms
+
+The details of the type, size, and semantics of the option will depend on the actual option, and will be documented with the option itself.
+
+TIP: It may be easier to use one of the typed forms of this function.
+
+`nng_stream_set`::
+This function is untyped, and can be used to configure any arbitrary data.
+The _val_ pointer addresses the data to copy, and _size_ is the size of the objected located at _val_.
+
+`nng_stream_set_bool`::
+This function is for options which take a Boolean (`bool`).
+
+`nng_stream_set_int`::
+This function is for options which take an integer (`int`).
+
+`nng_stream_set_ms`::
+This function is used to configure time durations (`nng_duration`).
+The duration is an integer number of milliseconds.
+
+`nng_stream_set_ptr`::
+This function is used to pass a pointer to structured data.
+The data referenced by is generally managed by other functions.
++
+NOTE: This form is somewhat special in that the object is generally not copied, but instead the *pointer* to the object is copied.
+Please see the documentation for the specific option for further details.
+
+`nng_stream_set_size`::
+This function is used to configure a size, typically for buffer sizes,
+message maximum sizes, and similar options.
+
+`nng_stream_set_string`::
+This function is used to pass configure a string.
+Strings passed this way must be legal UTF-8 or ASCII strings, terminated with a `NUL` (`\0`) byte.
+
+`nng_stream_set_uint64`::
+This function is used to configure a 64-bit unsigned value.
+
+`nng_stream_set_addr`::
+This function is used to configure a xref:../opts/nng_sockaddr.adoc[socket address].
+The value is copied, and thus the caller may discard the supplied value immediately after this function returns.
+
+### Return Values
+
+This function returns 0 on success, and non-zero otherwise.
+
+### Errors
+
+[horizontal]
+`NNG_ECLOSED`:: The connection is closed.
+`NNG_EINVAL`:: Either _data_ or _size_ are invalid.
+`NNG_ENOTSUP`:: The option is not supported.
+`NNG_EREADONLY`:: The option may not be modified.
