Netcomm missing libni_emb.so.6

Source code for the library?

What's the reason only binary .so file is included and not the whole source?

FRC_NetworkCommunication_CANSessionMux_sendMessage gives a status of -44089

I'm writing a simple CAN demo without WPILib. The title, I suppose, says it all.
My code:

int32_t createCANId(int deviceID, int deviceType, int manufacturerType, int32_t apiId) { // Shamelessly stolen from WPILib (and fixed to use sensible datatypes)
  int32_t createdId = 0;
  createdId |= ((int32_t)(deviceType) & 0x1F) << 24;
  createdId |= ((int32_t)(manufacturerType) & 0xFF) << 16;
  createdId |= (apiId & 0x3FF) << 6;
  createdId |= deviceID & 0x3F;
  return createdId;
}

void sendMessage(int id){
    uint8_t message[8] = {
        0, 0, 0, 0, 0, 0, 0, 0
    };
    int32_t status;
    FRC_NetworkCommunication_CANSessionMux_sendMessage(createCANId(id, 0, 0, 0), message, 8, 0, &status);
    if (status != 0){
        std::cout << "A can frame failed to send: " << (long)status << std::endl;
    }
    usleep(100000);
}

(Edited, as I'm not capable of disclosing some constant values)
