Another approach: - set poll timeout, SO_SNDTIMEO, and SO_RCVTIMEO as we did before, but return SD_RES_NETWORK_ERROR only if epoch is incremented after timeout. - call connect/2 with nonblocking, and wait for connect completion with poll to avoid a connect timeout problem. This may be easier than digging into kernel code. Thanks, Kazutaka -- sheepdog mailing list sheepdog@lists.wpkg.org http://lists.wpkg.org/mailman/listinfo/sheepdog
