NAME
forms - character based forms package
SYNOPSIS
#include <form.h>
DESCRIPTION
The form library is built using the curses library, and any program using
forms routines must call one of the curses initialization routines such
as initscr. A program using these routines must be compiled with -lform
and -lcurses on the cc command line.
The forms package gives the applications programmer a terminal-
independent method of creating and customizing forms for user-
interaction. The forms package includes: field routines, which are used
to create and customize fields, link fields and assign field types;
fieldtype routines, which are used to create new field types for
validating fields; and form routines, which are used to create and
customize forms, assign pre/post processing functions, and display and
interact with forms.
Current Default Values for Field Attributes
The forms package establishes initial current default values for field
attributes. During field initialization, each field attribute is
assigned the current default value for that attribute. An application
can change or retrieve a current default attribute value by calling the
appropriate set or retrieve routine with a NULL field pointer. If an
application changes a current default field attribute value, subsequent
fields created using new_field will have the new default attribute value.
(The attributes of previously created fields are not changed if a current
default attribute value is changed.)

RETURN VALUE
Routines that return a pointer always return NULL on error. Routines
that return an integer return one of the following:
E_OK - The function returned successfully.
E_CONNECTED - The field is already connected to a form.
E_SYSTEM_ERROR - System error.
E_BAD_ARGUMENT - An argument is incorrect.
E_CURRENT - The field is the current field.
E_POSTED - The form is posted.
E_NOT_POSTED - The form is not posted.
E_INVALID_FIELD - The field contents are invalid.
E_NOT_CONNECTED - The field is not connected to a form.
E_NO_ROOM - The form does not fit in the subwindow.
E_BAD_STATE - The routine was called from an
initialization or termination function.
E_REQUEST_DENIED - The form driver request failed.
E_UNKNOWN_COMMAND - An unknown request was passed to the the
form driver.
NOTES
The header file <form.h> automatically includes the header files <eti.h>
and <curses.h>.
