Re: [MiNT] Kentry
I'd like to add to kentry/kentry_module:
long _cdecl (*register_shutdown)(long _cdecl (*on_shutdown)(long mode));
Module (device driver or such) could register a function that can be executed
at system shutdown, or module unload. "mode" parameter can be following:
#define SHUTOWN 0 /* system is going down, all processes are killed, all file
descriptors closed */
#define UNLOAD 1 /* just unload module. System is fully operational and
should be operational after this function */
All other values are reserved. If on_shutdown function will get any other
value, it should exit at once returning E_OK.
on_shutdown return value should be E_OK if function succeded, or error value
if it didn't.
Yes, in this way it don't make much sense and it will not work (e.g. for
example to which module belongs the callback?). I planned such things for
an extended module interface. Dynamic unload of modules is a little bit
problematic as until now no kernel part track a reference if the module is
still in use (I'm sure a module unload should be denied if some kernel
data structures still reference it :-)).
