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 inte- ger. 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. SEE ALSO
ncurses(3NCURSES) and related pages whose names begin "form_" for detailed descriptions of the entry points. 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. AUTHORS
