.Sh DESCRIPTION
|
|
The
|
|
.Fn field_init
|
|
function returns a pointer to the function that will be called just
|
|
after the current field changes and just before the form is posted,
|
|
this function may be set by using the
|
|
.Fn set_field_init
|
|
function. Similarly, the function
|
|
.Fn field_term
|
|
will return a pointer to the function that will be called just before
|
|
the current field changes and just after the form is unposted, this
|
|
function pointer may be set by using the
|
|
.Fn set_field_term
|
|
function. The
|
|
.Fn form_init
|
|
function will return a pointer to the function that will be called
|
|
just before the form is posted to the screen, this function can be set
|
|
by calling the
|
|
.Fn set_form_init
|
|
function. The
|
|
.Fn form_term
|
|
function will return a pointer to the function that will be called
|
|
just after the form is unposted from the screen, this function may be
|
|
set by using the
|
|
.Fn set_form_term
|
|
function. By default, the init and term function pointers are NULL.
|
|
.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
|
