Manage path to resources folder with fmuResourceLocation

[V3nt1n]

Hello everyone,

My question is related to: How can we manage to define the path to the files stored in the resources folder?

I wasnt able to properly define it.

Please correct this piece of code (The idea is to access the data.txt file stored in the resources folder):

fmi2Component fmi2Instantiate(fmi2String instanceName, fmi2Type fmuType, fmi2String fmuGUID, fmi2String fmuResourceLocation,
                              const fmi2CallbackFunctions* functions, fmi2Boolean visible, fmi2Boolean loggingOn) {
    if (strcmp(fmuGUID, MODEL_GUID) != 0) {
        return NULL;
    }
    ModelInstance* instance = new ModelInstance();
    instance->input1 = 0.0;
    instance->output = 0.0;
    std::ifstream file(std::string(fmuResourceLocation) + "/data.txt"); // Read file from path, How to define it properly?
    std::string line;
    std::getline(file, line);
    instance->dvalue = std::stod(line);
    file.close();
    return instance;
}

Best regards & thnx for your answers
