form_field - make and break connections between fields and forms
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);
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 move the given field (which must be discon-
nected) to a specified location on the screen.
The function form_fields returns NULL on error.
The function field_count returns ERR (the general curses error return
value) on error.
The functions set_form_fields and move_field return one of the follow-
ing codes on error:
E_OK The routine succeeded.
System error occurred (see errno).
Routine detected an incorrect or out-of-range argument.
The form is already posted.
The field is already connected to a form.
The header file <form.h> automatically includes the header file
These routines emulate the System V forms library. They were not sup-
ported 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).
