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 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.
