fcntl (fd, F_SETOWN, getpid());
the user of the program will became the owner of the opened file
fcntl (fd, F_SETFL, fcntl (fd, F_GETFL, NULL) | O_ASYNC));
when somebody are reading / writing or delete your file, the operating
system will generate a SIGNAL to your program (default is SIGIO )
check man 2 fcntl for more detailed explanation.
