NAME
     field_init, field_term, form_init, form_term, set_field_init,
     set_field_term, set_form_init, set_form_term -- form library

LIBRARY
     Curses Form Library (libform, -lform)

SYNOPSIS
     #include <form.h>

     void (*)(FORM *)
     field_init(FORM *form);

     void (*)(FORM *)
     field_term(FORM *form);

     void (*)(FORM *)
     form_init(FORM *form);

     void (*)(FORM *)
     form_term(FORM *form);

     int
     set_field_init(FORM *form, void (*function)(FORM *));

     int
     set_field_term(FORM *form, void (*function)(FORM *));

     int
     set_form_init(FORM *form, void (*function)(FORM *));

     int
     set_form_term(FORM *form, void (*function)(FORM *));

DESCRIPTION
     The 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 set_field_init() function.
     Similarly, the function 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 set_field_term() function.  The 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
     set_form_init() function.  The 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 set_form_term()
     function.  By default, the init and term function pointers are NULL.

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:

     E_OK               The function was successful.
