Sending signals to user space program from kernel space

[rishi agrawal <postrishi@xxxxxxxxx>]

Hello Everyone,

I have a char device which when gets ioctl  case 'a' starts a for loop with index ' i '.

I want to send the value of index ' i ' to user space whenever ' i ' is even.

I want some thing like the kernel space code of char device should send a variable and also a 'signal' that it has send a value.

How can it be done ?

Its something like Pipes
