What's wrong with l buffersmall?

cout<<"-------------------------------"<<endl;
cout<<rus("Список товаров получен из файла")<<endl;

All functions are working, but when reading a file, it throws

File: f:\dd\vctools\crt_bld\self_x86\crt\ src\tcscpy_s.inl
Line: 30
Expression: (L "Buffer is too small" && 0)

Answer 1

You have too little buffer somewhere. Go under debugging and look at exactly where in your code this error occurs. Most likely it is in one of the strcpy_s.
