According to MSDN, line methods return LONG, which translates to Int32 in the .NET world. The possible error results, however, go over the capacity of a 32-bit integer. The header files show them as positive, but MSDN pages suggest that they are negative, which further suggests that perhaps they are meant to overflow. Because having variables overflow on purpose isn't very .NET-like, and C++ examples show that the result of this method is often assigned to a DWORD which translates to a UInt32 in .NET, it's safe to assume that we can have uint as the return type for this pinvoke.
