X/Open Curses, Issue 4, Version 2

The CURSES functions provide a terminal-independent method of updating character screens. A comprehensive API lets the application perform terminal operations: overall screen, window and pad manipulation, output to windows and pads; reading terminal input; control over terminal and CURSES input and output options; environment query functions; color manipulation; use of soft label keys; terminfo access; and access to low-level CURSES functions. This document supersedes Issue 4 and contains corrections and clarifications which have been suggested by industry feedback. In particular many of the functional prototypes have been corrected, and color handling has been further clarified.
