Re: corrected:what is fcntl function

[rinku rathore <rinku_ques@yahoo.com>]

hello,

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 )
basically fcntl handle the file descriptor that means
when system generate a Signal SIGIO it is handled by
that fd(file descriptor),passed as first argument can
I get more information about O_ASYNC
