Write the specified `value` to the specified output `stream` and return a reference to the modifiable `stream`.

== Synopsis

Declared in `<balb_testmessages.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]

template<class STREAM>

STREAM&
bdexStreamOut(
    STREAM& stream,
    xref:BloombergLP/balb/Enumerated/Value.adoc[Value] value,
    int version);
----

== Description

Optionally specify an explicit `version` format; by default, the maximum supported version is written to `stream` and used as the format. If `version` is specified, that format is used but _not_ written to `stream`. If `version` is not supported, `stream` is left unmodified. (See the package‐group‐level documentation for more information on `bdex` streaming of container types).

== Return Value

a reference to the modifiable `stream`
