X/Open Curses (XCURSES)

XCURSES is not part of the Base Specifications, Issue 7, but is a separate Open Group Technical Standard. XCURSES describes a set of interfaces providing a terminal-independent method of updating character screens that are available to application programs on systems conformant to this part of the Single UNIX Specification.

This document is structured as follows:

  • Chapter 1 introduces Curses and gives an overview of the changes made in this version. This chapter also defines the requirements for conformance to this document and shows the generic format followed by interface definitions in Chapter 4.

  • Chapter 2 describes the relationship between Curses and the C language, the compilation environment, and the X/Open System Interface (XSI) operating system requirements. It also defines the effect of the interface on the name space for identifiers and introduces the major data types that the interfaces use.

  • Chapter 3 gives an overview of Curses. It discusses the use of some of the key data types and gives general rules for important common concepts such as characters, renditions, and window properties. It contains general rules for the common Curses operations and operating modes. This information is implicitly referenced by the interface definitions in Chapter 4. The chapter explains the system of naming the Curses functions and presents a table of function families. Finally, the chapter contains notes regarding use of macros and restrictions on block-mode terminals.

  • Chapter 4 defines the Curses functional interfaces.

  • Chapter 5 defines the contents of headers which declare the functions and global variables, and define types, constants, macros, and data structures that are needed by programs using the services provided by the interfaces defined in Chapter 4.

  • Chapter 6 defines the Curses utilities.

  • Chapter 7 discusses the terminfo database which Curses uses to describe terminals. The chapter specifies the source format of a terminfo entry using a formal grammar, an informal discussion, and an example. Boolean, numeric, and string capabilities are presented in tabular form.

  • Appendix A discusses the use of these capabilities by the writer of a terminfo entry to describe the characteristics of the terminal in use.

  • The Glossary contains normative definitions of terms used in the document.
