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

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

the following codes on error:
E_OK The routine succeeded.
E_SYSTEM_ERROR

NOTES
The header file <form.h> automatically includes the header
1
form_field(3)form_field(3)
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).
