Dinstar DWG2000 SMS API stable release

I’ve finished the first stable release of the DWG2000 messaging API. I tested it dozens of times and appears stable after 24 hours of constant running. I’m aware of the memory leaks but I’ll fix this issue as soon as I can.

The code is pretty straightforward and self explanatory. By now this is just for personal use but if any of you are working with the same family of products, I can definitely help you. It is not ready for production, but it works.

int index = 0;

LOG(L_DEBUG, “tNumber of ports: %dn”, status->size);

for (index = 0; index < status->size; index++)
LOG(L_DEBUG, “tPort%d: %dn”, index, status->status_array[index].status);

void msg_response_handler(dwg_sms_response_t *response)
LOG(L_DEBUG, “tResponse from %sn”, response->number);

dwg_message_callback_t callbacks = {

dwg_start_server(7008, &callbacks);

str_t des = { “0981146623”, 10 };
str_t msg = { “hola”, 4 };

dwg_send_sms(&des, &msg);

  1. Hi.
    I’m have Dinstar DWG 2000 and develop sms application on C# but dll not work. You can build dll files bindding for C# . Please


    • I can do that. In fact, I was working on it but I stopped the implementation because the project switched its direction. Are you working on Linux?

  2. I’m working on Windows . You can shared library write on C# to me. Please
    I’m test application but not work on windows 🙂

  3. Thank for your work! I have the same requiement for C# I have c++ source code from Dinstar but cannot use DLL in C#. Please if you just have DLLImport declarations, I will be thankfull to receive it
