The function form_opts() returns the current options that are set on the given form. The
form_opts_off() will turn off the form options given in options for the form, similarly,
form_opts_on() will turn on the options specified in options for the given form. The form
options can be set to an explicit set by calling set_form_opts().
The following form options are valid:
O_BS_OVERLOAD If this option is set and the cursor is at the first character in the field
then the backspace character will perform the same function as a
REQ_PREV_FIELD driver request, moving to the previous field in the form.
O_NL_OVERLOAD If this option is set and the cursor is at the end of the field then the new
line character will perform the same function as a REQ_NEXT_FIELD driver
request, moving to the next field in the form.
By default no form options are set.
Functions returning pointers will return NULL if an error is detected. The functions that
return an int will return one of the following error values:
E_OK The function was successful.
The header <form.h> automatically includes both <curses.h> and <eti.h>.
