smx++

smx++ is a C++ class library which rests on top of smx. The smx++ Application Program Interface (API) is designed to mirror smx yet be simpler and easier to use. In most cases, smx++ methods call their smx counterparts for system services. smx++ enhances the use of Intel 80x86 embedded processors with C++.
A chief advantage of smx++ is that it provides a simpler API which meets most user requirements. With this in mind, several seldom-used smx features and functions have been omitted. Yet, since smx underlies smx++, direct smx calls are still possible. This feature eases the transition from C to C++ by permitting a mix of C and C++ application modules. smx++ supports Borland C++ and Microsoft C++.
From the C++ developer¦s perspective, the enticing aspect of smx++ is that it allows him to create his own objects, by inheritance, from smx++ classes. For example, device drivers can be derived from the Bucket and Pipe classes (which, in turn, have been derived from the Software I/O bus (SIObus) class.) Process classes can be derived from a mixture of smx++ objects to perform specific work functions. Actual processes (objects) can be conveniently created when needed and deleted when not needed.
smx++ consists of 9 base classes and 7 derived classes. The class hierarchy is deliberately shallow in order to achieve the speed necessary for real-time systems.
