The Platform module provides a common interface to platform-specific functionality, such as memory allocation, resource locking, interrupts, signalling, and others.
The Platform object provides low-level platform-specific functionality and depends upon the combination of the operating system and the C compiler used for development. The Platform module was written to provide platform-independent access functions for use by the MPI. Unless your application needs to be written for compatibility with different platforms, MEI encourages the use of OS-specific functions. If an MEIPlatform object handle is required, one should obtain this handle from the MPIControl method meiControlPlatform.
Do NOT attempt to use the (intentionally undocumented) method, meiPlatformCreate(). Using this method will interfere with the inner workings of the MPI.
The meiObjectGive/Take(...) methods all use the meiPlatformLockGive/Take(...) methods. When you take a lock, you take exclusive access to the resource (i.e., the section of XMP firmware memory associated with that Object). When you give a lock, you release (give up) that exclusive access. Think of it as TakeAccessOf and GiveUpAccess.
