From 25e5e4c7e9d5ec3e95c9526d1abaca40ada50ab0 Mon Sep 17 00:00:00 2001 From: Michael Tokarev Date: Wed, 14 Mar 2012 11:18:54 +0400 Subject: rewrite iov_send_recv() and move it to iov.c Make it much more understandable, add a missing iov_cnt argument (number of iovs in the iov), and add comments to it. The new implementation has been extensively tested by splitting a large buffer into many small randomly-sized chunks, sending it over socket to another, slow process and verifying the receiving data is the same. Also add a unit test for iov_send_recv(), sending/ receiving data between two processes over a socketpair using random vectors and random sizes.
