+
+ This manual page describes functions which may appear in

+ configurations of the library:
+
+ ncurses
+ the "normal" library, which handles 8-bit
+ characters. The normal (8-bit) library stores
+ characters combined with attributes in chtype
+ data.
+
+ Attributes alone (no corresponding character)
+ may be stored in chtype or the equivalent
+ attr_t data. In either case, the data is
+ stored in something like an integer.
+
+ Each cell (row and column) in a WINDOW is
+ stored as a chtype.
+
+ ncursesw
+ the so-called "wide" library, which handles
+ multibyte characters (see the section on
+ ALTERNATE CONFIGURATIONS). The "wide" library
+ includes all of the calls from the "normal"
+ library. It adds about one third more calls
+ using data types which store multibyte charac-
+ ters:
+
+ cchar_t
+ corresponds to chtype. However it is a
+ structure, because more data is stored
+ than can fit into an integer. The char-
+ acters are large enough to require a full
+ integer value - and there may be more
+ than one character per cell. The video
+ attributes and color are stored in sepa-
+ rate fields of the structure.
+
+ Each cell (row and column) in a WINDOW is
+ stored as a cchar_t.
+
+ wchar_t
+ stores a "wide" character. Like chtype,
+ this may be an integer.
+
+ wint_t
+ stores a wchar_t or WEOF - not the same,
+ though both may have the same size.
+
+ The "wide" library provides new functions
+ which are analogous to functions in the "nor-
+ mal" library. There is a naming convention
+ which relates many of the normal/wide vari-
+ ants: a "_w" is inserted into the name. For
+ example, waddch becomes wadd_wch.
