Our requirement is we need to do timer operations in kernel = mode. For achieving this, first we tried with system calls ( setitimer = ). while compiling only it has given error that is undefined = referrence, i had include signal.h with path, still its not compiling. = Then I thought that it might be a system call and it only used in user = mode. am i right? I searched in web wastly, but could not find a single = material on how to do timer operations in kernel mode. I have gone = thru the code which is under /sys/svr4 which is related to = implementation of system calls, which contains the timer operations code = too. Can I use this ? If yes how to proceed ? If i can not ? how I = have to proceed ?
