forms(S)


forms -- character-based-forms package

Syntax

cc ...-lform -lcurses

#include <form.h>

Description

The forms(S) library is built using the curses(S) library. Any program using forms routines must call one of the curses( ) initialization routines such as initscr(S).

The forms package gives the application programmer a terminal-independent way to create and customize forms for user interaction. The forms package includes:

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 a 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(S) have the new default attribute value. (The attributes of previously created fields are not changed if a current default attribute value is changed.)

Routine name index

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

Return values

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 form driver

Warning

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