+nng_stream_set - set option on byte stream

+
+int nng_stream_set(nng_stream *s, const char *name, const void *data, size_t size);

+
+----
+
+== DESCRIPTION
+
+The `nng_stream_set()` functions are used to configure options for the
+xref:nng_stream.5.adoc[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:nng_options.5.adoc[nng_options(5)].
+
+Additionally some transport-specific and protocol-specific options are
+documented with the transports and protocols themselves.
+
+=== 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_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_.
++
+TIP: It may be easier to use one of the typed forms of this function.
+
+`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 (such as timeouts) using
+the type
+xref:nng_duration.5.adoc[`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.
+For example, TLS configuration objects created with
+xref:nng_tls_config.3tls.adoc[`nng_tls_config_alloc()`]
+can be passed this way.
++
+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.
+(Other constraints may apply as well, see the documentation for each option
+for details.)
+
+`nng_stream_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_set_addr()`::
+This function is used to configure a
+xref:nng_sockaddr.5.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.
