Implementations of File Locking Mechanisms, Linux and Windows

The world of Operating Systems has evolved a lot, especially these late years, mainly due to technology in hardware, but also because of ever growing user and market requirements. Anyway, some basic concepts and implementations are still stuck around like they're irreplaceable. File locking is one of them. The point is, why in a range of more than 15 years, file locking mechanisms have little or not at all evolved, while the technology in general or OS-s particularly have changed a lot? That's why we'll discuss File locking mechanisms in Windows and Linux, and possibly find a better solution combining Linux Advisory Locking and Windows Mandatory Locking. The goal is to make this mechanism robust, and more important: cross-OS portable.
