Sending signal to User Application
 

Dear Friends,

What is the difference between SI_USER, SI_KERNEL and SI_QUEUE signal codes when used in context with real time application? I tried over the internet but couldn't get much information.

I am using send_sig_info function into the driver to send the signal to the registered PID process passed in the third argument of this function.

In addition, which signal codes to use in what type of application?

Thank you,
Ankur.
