Q14 - Interface Standards Informal Technical Data, Ada Interfaces to POSIX

Abstract

This report considers the applicability of the Portable Operating System Interface (POSIX) to the development of the Software Engineering Environment (SEE) for the Software Technology for Adaptable, Reliable Systems (STARS) program. It compares and contrasts characteristics and potential overlap of object management interfaces (in this example, CAIS-A) and POSIX. Because there are overlaps in the objectives for POSIX and an object manager, there are some apparent overlaps in the functions provided by the interfaces. It is concluded that there is no actual overlap in function in the I/O model for persistent data nor in the execution control models. Interfaces like CAIS-A should be the portable interface set for tools, while POSIX offer a method for gaining portability for the CAIS and other interfaces in the base level of the SEE.
