Chapter 3 System Services

This chapter describes the system services interface functions for the Microsoft Windows operating system. These functions access code and data in modules, allocate and manage both local and global memory, manage tasks, load program resources, translate strings from one character set to another, alter the Windows initialization file, assist in system debugging, carry out communications through the system's input and output (I/O) ports, create and open files, and create sounds using the system's sound generator.
