Assign a `bsl::vector<int>` read from `stream` to `variable`.

== Synopsis

Declared in `<bslx_instreamfunctions.h>`

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

template<
    class STREAM,
    class ALLOC>
STREAM&
bdexStreamIn(
    STREAM& stream,
    xref:bsl/vector-00d.adoc[bsl::vector<int, ALLOC>]& variable,
    int version);
----

== Description

Assign to the specified `variable` the `bsl::vector<int, ALLOC>` value read from the specified input `stream`, and return a reference to `stream`. The specified `version` is ignored. If `stream` is initially invalid, this operation has no effect. If `stream` becomes invalid during this operation, `variable` has an undefined, but valid, state. See the `bslx` package‐level documentation for more information on BDEX streaming of value‐semantic types and containers.

== Return Value

a reference to `stream`

== Parameters
