I use sendfile(socket_fd, file_fd, &offset, left_size) at linux-2.6.20-1.21 to send a symbol link file by non-block socket. The sendfile() is blocking when the file size is too large(100K+).
How can I solve this problem?

do you check the error code? Is it success or something like `EAGAIN`? – Marcus Müller Aug 27 '15 at 15:11

The `sendfile()` is blocking and not return! – sfzhang Aug 27 '15 at 15:15
