hi,
Hi
  we are developing an application which ultimately leades to change in =
kernel. 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 ?

Please help me
