Hi all, I read one statement in LDD in 6th chapter about interrupt. "The current pointer is not valid in interrupt mode and can't be used". I am not able to get it. Can anybody plz explain me what author want to convey by using above statement. Also i have one confusion. After processing an interrupt i.e. executing an interrupt handler routine will it continoues to execute the same process or context switch is possible to happen and after that it will wake up a blocked process like a driver waiting for some event. thanks in advance, Deepak Joshi ___________________________________________________________ How much free photo storage do you get?
