decimal64FromMultiWidthEncodingIfValid(
    xref:BloombergLP/bdldfp/Decimal64.adoc[Decimal64]* decimal,
    unsigned char const* buffer,
    xref:BloombergLP/bsls/Types/size_type.adoc[bsls::Types::size_type] size);
----

== Description

The behavior is undefined unless `buffer` has at least `size` bytes. Note that this function returns a non‐zero value and leaves `decimal` unchanged if `size` is not a valid encoding size of the _multi‐width encoding_ format.

== Return Value

0 on success, and a non‐zero value otherwise

== Parameters

[cols="1,4"]
