do not provide a <code>profil()</code> system call. On such a system,
arrangements are made for the kernel to periodically deliver
a signal to the process (typically via <code>setitimer()</code>),
which then performs the same operation of examining the
program counter and incrementing a slot in the memory array.
Since this method requires a signal to be delivered to
user space every time a sample is taken, it uses considerably
more overhead than kernel-based profiling. Also, due to the
added delay required to deliver the signal, this method is
less accurate as well. <br></p><p><br></p><p><br></p><p>whether we can change value of an interval timer used for profiling ?<br></p><p><br></p>
