Module `Curses`Source

* Bindings to the ncurses library. * * Beware, all coordinates are passed y first, then x. * * Functions whose name start with a "w" take as first argument the window the * function applies to. * Functions whose name start with "mv" take as first two arguments the * coordinates y and x of the point to move the cursor to. For example * mvaddch y x ch is the same as move y x; addch ch.

Sourcetype window

Windows.

Sourcetype screen

Screens.

Sourcetype terminal

Terminals.

Sourcetype chtype = int

Characters. Usual characters can be converted from/to chtype using * char_of_int and int_of_char. See also get_acs_codes for characters * useful for drawing and the Key module for special input characters.

Sourcetype attr_t = int

Attributes are lorings of flags which are defined in the A module.

Sourcetype err = bool

A return value. false means that an error occured.
