OS/2 2.X Control Program API

Application programming interfaces (APIs) allow developers and programmers to create and customize applications. The control program API is used for the most basic of programming functions, like memory management, file handling and timing. This guide places all control program APIs into logical groups, with brief descriptions of each concept before each grouping. The text contains lists of system resources and systems limits required for every function, saving programmers time by letting them predict if a function will fit in the space available. The book also discusses undocumented features that are currently available only by word of mouth.
