Platform Objects
Introduction
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 MPIPlatform object handle is required, one should obtain this handle from the MPIControl method mpiControlPlatform.
The mpiObjectGive/Take(...) methods all use the mpiPlatformLockGive/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.
