NAME

       form_field - make and break connections between fields and forms

SYNOPSIS

       #include <form.h>

       int set_form_fields(FORM *form, FIELD **fields);
       FIELD **form_fields(const FORM *form);
       int field_count(const FORM *form);
       int move_field(FIELD *field, int frow, int fcol);

DESCRIPTION

       The  function  set_form_fields  changes  the  field  pointer  array of the given form.  The array must be
       terminated by a NULL.

       The function form_fields returns the field array of the given form.

       The function field_count returns the count of fields in form.

       The function move_field moves the given field (which must be disconnected) to a specified location on the
       screen.

RETURN VALUE

       The function form_fields returns a pointer (which may be NULL).  It does not set errno.

       The function field_count returns ERR if the form parameter is NULL.

       The functions set_form_fields and move_field return one of the following codes on error:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_CONNECTED
            The field is already connected to a form.

       E_POSTED
            The form is already posted.

       E_SYSTEM_ERROR
            System error occurred (see errno(3)).

PORTABILITY

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

       The SVr4 forms library documentation specifies the field_count error value as -1 (which is the  value  of
       ERR).
