Within the text at appropriate points, we contrast Windows style and functionality with the comparable UNIX (and Linux) and ANSI Standard C library features. As mentioned, Appendix B presents tables listing these comparable functions. This information is included because many readers are familiar with UNIX and are interested in the comparisons between the two systems. Readers without a UNIX background should feel free to skip those paragraphs in the text, which are indented and set in a smaller font.
