decimal64FromMultiWidthEncodingIfValid(
Decimal64* decimal,
unsigned char const* buffer,
bsls::Types::size_type size);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.
