My guess, because of this: ----------------- The accept4() system call is available starting with Linux 2.6.28; support in glibc is available starting with version 2.10. ----------------- So, it's only a matter of time before we get bitten by this one too. Probably prudent to do all of them the same way as epoll_create(). -- Bojan
