hi,
I read the post http://lkml.org/lkml/2002/12/18/218 about how to deal
with the restarting system call. But still cannot get it.
Maybe, the basic question should be what is a "restarting system call".
Some system calls can be interrupted by signals and return EINTR
before completing their work. You can use sigaction() with the
SA_RESTART flag to make it so that after the signal handler is called
the system call is automatically restarted.
Can anyone here give me any hints?
see "man 2 sigaction", and this page may also be of use to you:

"Interrupted system calls".
