NAME

-       form_hook - set hooks for automatic invocation by applica-
-       tions
-

-

SYNOPSIS

-       #include <form.h>
-       int set_field_init(FORM *form, void (*func)(FORM *));
-       void (*)(FORM *) field_init(const FORM *form);
-       int set_field_term(FORM *form, void (*func)(FORM *));
-       void (*)(FORM *) field_term(const FORM *form);
-       int set_form_init(FORM *form, void (*func)(FORM *));
-       void (*)(FORM *) form_init(const FORM *form);
-       int set_form_term(FORM *form, void (*func)(FORM *));
-       void (*)(FORM *) form_term(const FORM *form);

DESCRIPTION

-       These functions make it possible to set hook functions  to
-       be called at various points in the automatic processing of
-       input event codes by form_driver.
-
-       The function set_field_init sets a hook to  be  called  at
-       form-post  time  and  each time the selected field changes
-       (after the change).  field_init returns the current  field
-       init hook, if any (NULL if there is no such hook).
-
-       The  function  set_field_term  sets a hook to be called at
-       form-unpost time and each time the selected field  changes
-       (before the change).  field_term returns the current field
-       term hook, if any (NULL if there is no such hook).
-
-       The function set_form_init sets a hook  to  be  called  at
-       form-post  time  and  just  after a page change once it is
-       posted.  form_init returns the current form init hook,  if
-       any (NULL if there is no such hook).
-
-       The  function  set_form_term  sets  a hook to be called at
-       form-unpost time and just before a page change once it  is
-       posted.   form_init returns the current form term hook, if
-       any (NULL if there is no such hook).

RETURN VALUE

-       Routines that return pointers return NULL on error.  Other
-       routines return one of the following:
-
-       E_OK The routine succeeded.
-
-       E_SYSTEM_ERROR
-            System error occurred (see errno).
-
-

SEE ALSO

-       curses(3x), form(3x).

-

NOTES

-       The header file <form.h> automatically includes the header
-       file <curses.h>.
-
-
-
-

PORTABILITY

-       These routines emulate the System V forms  library.   They
-       were not supported on Version 7 or BSD versions.
