NAME
forms - character based forms package
SYNOPSIS
cc [flag . . .] file -lform -lcurses [library . . .]
#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.
