NAME

form - curses extension for programming forms  

SYNOPSIS

#include <form.h>
 

DESCRIPTION

The form library provides terminal-independent facilities for composing form screens on character-cell terminals. The library includes: field routines, which create and modify form fields; and form routines, which group fields into forms, display forms on the screen, and handle interaction with the user.

The form library uses the curses libraries. To use the form library, link with the options -lform -lcurses.

Your program should set up the locale, e.g.,


     setlocale(LC_ALL, "");

so that input/output processing will work.

A curses initialization routine such as initscr must be called before using any of these functions.  

Current Default Values for Field Attributes

The form library maintains a default value for field attributes. You can get or set this default by calling the appropriate set_ or retrieval routine with a NULL field pointer. Changing this default with a set_ function affects future field creations, but does not change the rendering of fields already created.  

Routine Name Index

The following table lists each form routine and the name of the manual page on which it is described.

RETURN VALUE

Routines that return pointers return NULL on error, and set errno to the corresponding error-code returned by functions returning an integer. Routines that return an integer return one of the following error codes:
E_OK
The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_BAD_STATE
Routine was called from an initialization or termination function.
E_CONNECTED
The field is already connected to a form.
E_INVALID_FIELD
Contents of a field are not valid.
E_NOT_CONNECTED
No fields are connected to the form.
E_NOT_POSTED
The form has not been posted.
E_NO_ROOM
Form is too large for its window.
E_POSTED
The form is already posted.
E_REQUEST_DENIED
The form driver could not process the request.
E_SYSTEM_ERROR
System error occurred (see errno).
E_UNKNOWN_COMMAND
The form driver code saw an unknown request code.
 

NOTES

The header file <form.h> automatically includes the header files <curses.h> and <eti.h>.

In your library list, libform.a should be before libncurses.a; that is, you want to say `-lform -lncurses', not the other way around (which would give you a link error using most linkers).  

PORTABILITY

These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.
