One way would be to use the SIOCOUTQ ioctl on the TCP socket. This states how many un-ACK'd (and thus unfree'd) bytes remain in the send queue. So, for example, let's say you did two 1K sends, and you just want to know when the first 1K is reusable. To do that, just wait for SIOCOUTQ to return 1K. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
