Information about task_struct structure

["Anjaneyulu" <anjaneyulu@mistralsoftware.com>]

Hi,

I would like to know when

int (*notifier)(void *priv);
void *notifier_data;
in the struct task_struct used.

 

These are defined under comment signal handler.

Does this mean that they will be only used when i use signal with that task????

If yes, can i use notifier_data to store my data (when signals not used)????

 

 

Thanks in advance.

Regards,

Anj
