forms(3X)                        UNIX System V                        forms(3X)


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.)

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

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.
