NAME
form_hook, set_form_init, form_init, set_form_term, form_term, set_field_init, field_init, set_field_term, field_term - assign application- specific routines for invocation by forms
SYNOPSIS
cc [ flag... ] file... -lform -lcurses [ library... ] #include <form.h> int set_form_init(FORM *form, void (*func)(FORM*)); void (*form_init)(FORM *form); int set_form_term(FORM *form, void (*func)(FORM*)); void (*form_term)(FORM *form); int set_field_init(FORM *form, void (*func)(FORM*)); void (*field_init)(FORM *form); int set_field_term(FORM *form, void (*func)(FORM*)); void (*field_term)(FORM *form);
DESCRIPTION
These routines allow the programmer to assign application specific routines to be executed automatically at initialization and termination points in the forms application. The user need not specify any application-defined initialization or termination routines at all, but they may be helpful for displaying messages or page numbers and other chores. set_form_init() assigns an application-defined initialization function to be called when the form is posted and just after a page change. form_init() returns a pointer to the initialization function, if any. set_form_term() assigns an application-defined function to be called when the form is unposted and just before a page change. form_term() returns a pointer to the function, if any. set_field_init() assigns an application-defined function to be called when the form is posted and just after the current field changes. field_init() returns a pointer to the function, if any. set_field_term() assigns an application-defined function to be called when the form is unposted and just before the current field changes. field_term() returns a pointer to the function, if any.
RETURN VALUES
Routines that return pointers always return NULL on error. Routines that return an integer return one of the following: E_OK The function returned successfully. E_SYSTEM_ERROR System error.
