SFileSetFilePointer error when new pointer is <0

Browse Source 
The standard behaviour for fseek / SetFilePointer when the new pointed value would be negative is to not move the pointer and return an error.
See : https://msdn.microsoft.com/en-us/library/windows/desktop/aa365541(v=vs.85).aspx `If a new file pointer is a negative value, the function fails, the file pointer is not moved, and the code returned by GetLastError is ERROR_NEGATIVE_SEEK.`
