This chapter contains an alphabetic list of the Control Program functions available in the OS/2 operating system. These functions can be used in full-screen, windowed (VIO), and Presentation Manager sessions to perform basic operating-system functions, such as file input and output, memory allocation, thread control and communication, process control and communication, pipe and queue manipulation, and exception and error handling.
