The ncurses package was originated by Pavel Curtis. The original
maintainer of the package is Zeyd Ben-Halim <zmbenhal@netcom.com>.
Eric S. Raymond <esr@snark.thyrsus.com> wrote many of the new features

Terminology
In order to use the library, it is necessary to have certain types and
variables defined. Therefore, the programmer must have a line:
-
#include <curses.h>
at the top of the program source. The screen package uses the Standard
order to avoid clumsiness, most I/O routines can be preceded by the
prefix 'mv' and the desired (y, x) coordinates prepended to the
arguments to the function. For example, the calls
-
move(y, x);
addch(ch);
The curses library sets some variables describing the terminal
capabilities.
-
type name description
------------------------------------------------------------------
int LINES number of lines on the terminal
Your panels-using modules must import the panels library declarations
with
-
#include <panel.h>
and must be linked explicitly with the panels library using an -lpanel
Compiling With the menu Library
Your menu-using modules must import the menu library declarations with
-
#include <menu.h>
and must be linked explicitly with the menus library using an -lmenu
Compiling With the form Library
Your form-using modules must import the form library declarations with
-
#include <form.h>
and must be linked explicitly with the forms library using an -lform
There is also a large collection of field option bits you can set to
control various aspects of forms processing. You can manipulate them
with these functions:
-
int set_field_opts(FIELD *field, /* field to alter */
int attr); /* attribute to set */
Each field structure contains one character pointer slot that is not
used by the forms library. It is intended to be used by applications
to store private per-field data. You can manipulate it with:
-
int set_field_userptr(FIELD *field, /* field to alter */
char *userptr); /* mode to set */
by the user's editing actions on that field. It's sometimes useful to
be able to set the value of the zero-numbered (or some other) buffer
from your application:
-
int set_field_buffer(FIELD *field, /* field to alter */
int bufindex, /* number of buffer to alter */
char *value); /* string value to set */
The form dimensions are passed back in the locations pointed to by the
arguments. Once you have this information, you can use it to declare
of windows, then use one of these functions:
-
int set_form_win(FORM *form, /* form to alter */
WINDOW *win); /* frame window to connect */
