the return value of error is -1, EINTR is 4. Also, it keeps printing ": Resource temporarily unavailable" though I don't have any error statement to be printed. This is increasing CPU usage Abhinav On Sun, Dec 11, 2011 at 7:48 AM, <rixed () happyleptic org> wrote:
I did not remember what select() uses to return the readable file descriptors, but I do remember that any select can be interrupted while still waiting, and that the error is then EINTR, so you have to catch this particular error and ignore it (ie. merely loop on it). Googling for "non-restartable system call" may provide you with more detail. - This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
