dictionary load problem

Hello, everyone. Currently I encounter some question on using reuter dictionary. My sample code as follows:

thomsonreuters::ema::rdm::DataDictionary fid_dict_;
map<Int16, const emardm::DictionaryEntry*>   map_fid_dict_;

fid_dict_.loadFieldDictionary(dict_file.c_str());
fid_dict_.loadEnumTypeDictionary(enum_file.c_str());

const emaaccess::EmaVector<emardm::DictionaryEntry>& vec_entry = fid_dict_.getEntries();
for(unsigned i = 0; i < vec_entry.size(); i++)
{
    const emardm::DictionaryEntry* ptr = &(vec_entry[i]);
    map_fid_dict_[ vec_entry[i].getFid() ] = ptr;
    LOG_DEBUG("acronym:%s, ddeAcronym:%s, fid:%d, rippleToField:%d, fieldType:%d, length:%d, "
        "enumLength:%d, rwfType:%d, rwfLength:%d", 
        ptr->getAcronym().c_str(), ptr->getDDEAcronym().c_str(), ptr->getFid(),
        ptr->getRippleToField(), ptr->getFieldType(), ptr->getLength(),
        ptr->getRwfType(), ptr->getRwfLength());
}

The sample code load field dictionary and enum type dictionary from RDMFieldDictionary and enumtype.def which are shipped with EMA SDK. But when using LOG_DEBUG print certain field value, it seems the RwfType and RwfLength is unitialized at this moment, for example I got following output for BIDSIZE field:

Debug: acronym:BIDSIZE, ddeAcronym:BID SIZE, fid:30, rippleToField:0, fieldType:1, length:15, enumLength:8, rwfType:7, rwfLength:30603272

But later when I use map_fid_dict to fetching DictonaryEntry info for adding data into FieldList, I print the entry for BIDSIZE again like this:

Debug: BIDSIZE with type:1, fid:30, rwfType:8, length:7

The latter is right according to RDMFieldDictionary file. But why the previous printed rwf type & length is incorrect at that moment? My code has no further modification to map_fid_dict after load dictionary file. Many thanks.

    The number of format characters and variables mismatch.

    There are nine format characters in the format string but there are only eight values.

    1. ptr->getAcronym().c_str() => acronym:%s
    2. ptr->getDDEAcronym().c_str() => ddeAcronym:%s
    3. ptr->getFid() => fid:%d
    4. ptr->getRippleToField() => rippleToField:%d
    5. ptr->getFieldType() => fieldType:%d
    6. ptr->getLength() => length:%d
    7. => enumLength:%d
    8. ptr->getRwfType() => rwfType:%d
    9. ptr->getRwfLength() => rwfLength:%d

    You need to add ptr->getEnumLength().

    printf("acronym:%s, ddeAcronym:%s, fid:%d, rippleToField:%d, fieldType:%d, length:%d, "
                    "enumLength:%d, rwfType:%d, rwfLength:%d\n",
                    ptr->getAcronym().c_str(), ptr->getDDEAcronym().c_str(), ptr->getFid(),
                    ptr->getRippleToField(), ptr->getFieldType(), ptr->getLength(),
                    ptr->getEnumLength(),
                    ptr->getRwfType(), ptr->getRwfLength());

    The output is:

    acronym:PROD_PERM, ddeAcronym:PERMISSION, fid:1, rippleToField:0, fieldType:1, length:5, enumLength:0, rwfType:4, rwfLength:2
    acronym:RDNDISPLAY, ddeAcronym:DISPLAYTEMPLATE, fid:2, rippleToField:0, fieldType:1, length:3, enumLength:0, rwfType:4, rwfLength:1
    acronym:DSPLY_NAME, ddeAcronym:DISPLAY NAME, fid:3, rippleToField:0, fieldType:5, length:16, enumLength:0, rwfType:19, rwfLength:16
    acronym:RDN_EXCHID, ddeAcronym:IDN EXCHANGE ID, fid:4, rippleToField:0, fieldType:6, length:3, enumLength:3, rwfType:14, rwfLength:1
    acronym:TIMACT, ddeAcronym:TIME OF UPDATE, fid:5, rippleToField:0, fieldType:7, length:5, enumLength:0, rwfType:10, rwfLength:5
    acronym:TRDPRC_1, ddeAcronym:LAST, fid:6, rippleToField:7, fieldType:4, length:17, enumLength:0, rwfType:8, rwfLength:7
    acronym:TRDPRC_2, ddeAcronym:LAST 1, fid:7, rippleToField:8, fieldType:4, length:17, enumLength:0, rwfType:8, rwfLength:7
    acronym:TRDPRC_3, ddeAcronym:LAST 2, fid:8, rippleToField:9, fieldType:4, length:17, enumLength:0, rwfType:8, rwfLength:7
    acronym:TRDPRC_4, ddeAcronym:LAST 3, fid:9, rippleToField:10, fieldType:4, length:17, enumLength:0, rwfType:8, rwfLength:7

    I did a quick test your codes to print the dict. I just changed LOG_DEBUG to use normal cout and use static_cast when display integer value and then get a correct output according to the dic I load.

    cout << "acronym:" << ptr->getAcronym().c_str() <<"\tddeAcronym:" << ptr->getDDEAcronym().c_str() << "\tfid:" << static_cast<int>(ptr->getFid()) << "\trippleToField:" << (int)ptr->getRippleToField() << "\tfieldType:" << static_cast<int>(ptr->getFieldType()) << "\tlength:" << static_cast<int>(ptr->getLength()) << "\tenumLength:" << static_cast<int>(ptr->getEnumLength()) << "\trwfType:" << static_cast<int>(ptr->getRwfType()) << "\trwfLength:" << static_cast<int>(ptr->getRwfLength()) << "\n";

    Below is dictionary and sample output from the codes.

    @jirapongse.phuriphanvichai @moragodkrit.chumsri_1 Thank you all. As jirapongse.phuriphanvichai replied, it's a problem of printf formatting. Sorry for my carelessness, and thanks you two again.
