|
|

|
|
.Fn form_opts "FORM *form"

|
|
.Sh DESCRIPTION
|
|
The function
|
|
.Fn form_opts
|
|
returns the current options that are set on the given form. The
|
|
.Fn form_opts_off
|
|
will turn off the form options given in
|
|
.Fa options
|
|
for the form, similarly,
|
|
.Fn form_opts_on
|
|
will turn on the options specified in
|
|
.Fa options
|
|
for the given form. The form options can be set to an explicit set by
|
|
calling
|
|
.Fn set_form_opts .
|
|
.Sh PARAMETERS
|
|
The following form options are valid:
|
|
.Pp
|
|
.Bl -tag -width O_BS_OVERLOAD -compact
|
|
.It 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.
|
|
.It 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.
|
|
.El
|
|
.Pp
|
|
By default no form options are set.
|
|
.Sh RETURN VALUES
|
|
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:
|
|
.Pp
|
|
.Bl -tag -width E_UNKNOWN_COMMAND -compact
|
|
.It Er E_OK
