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

NOTES
The header file <form.h> automatically includes the header file <curses.h>.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).
