values as: 0 for successfull, -1 when cannot find the board, -2 when cannot load the kernel and so on. The first function, Initialize_HL return 0, and it means that is ok, the function LoadUser_HL (the second function that I need to call)also returns 0, and it is ok. I send an e-mail to the fabricant, and it tell me that, if these two functions worked fine, i.e, returns 0, every is ok untill here. But in LoadUser_HL, I when I initialize my Structure object, the return value is 0, but the my Structure object HSymTbl is not initialized, because I cannot find the symbols that I would be able to find (as _aicreg). So, I think that the problem is in the LoadUser_HL, but I dont get errors, and by messages that I get, everything looks like ok. The function where se symbol is not found is K_Move_Data_HL. The C++ source code is provided by fabricant, I do not have Visual C++ to compile it, but the executable provided works well.
