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.
The following table lists the available functions.
