/* DESCRIPTION */
/* */
/* This file contains data type definitions that make the ThreadX */
/* real-time kernel function identically on a variety of different */
/* processor architectures. For example, the size or number of bits */
/* in an "int" data type vary between microprocessor architectures and */
/* even C compilers for the same microprocessor. ThreadX does not */
/* directly use native C data types. Instead, ThreadX creates its */
/* own special types that can be mapped to actual data types by this */
/* file to guarantee consistency in the interface and functionality. */
