+ The <STRONG>ncurses</STRONG> library also provides many useful extensions,

+
+ This manual page describes functions which may appear in
+ any configuration of the library. There are two common
+ configurations of the library:
+
+ ncurses
+ the "normal" library, which handles 8-bit
+ characters. The normal (8-bit) library stores
+ characters combined with attributes in <STRONG>chtype</STRONG>
+ data.
+
+ Attributes alone (no corresponding character)
+ may be stored in <STRONG>chtype</STRONG> or the equivalent
+ <STRONG>attr_t</STRONG> data. In either case, the data is
+ stored in something like an integer.
+
+ Each cell (row and column) in a <STRONG>WINDOW</STRONG> is
+ stored as a <STRONG>chtype</STRONG>.
+
+ ncursesw
+ the so-called "wide" library, which handles
+ multibyte characters (See the section on
+ <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>). 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:
+
+ <STRONG>cchar_t</STRONG>
+ corresponds to <STRONG>chtype</STRONG>. 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 <STRONG>WINDOW</STRONG> is
+ stored as a <STRONG>cchar_t</STRONG>.
+
+ <STRONG>wchar_t</STRONG>
+ stores a "wide" character. Like <STRONG>chtype</STRONG>,
+ this may be an integer.
+
+ <STRONG>wint_t</STRONG>
+ stores a <STRONG>wchar_t</STRONG> or <STRONG>WEOF</STRONG> - 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, <STRONG>waddch</STRONG> becomes <STRONG>wadd_wch</STRONG>.
