From: Ken Brown <kbrown@sourceware.org> To: cygwin-cvs@sourceware.org Subject: [newlib-cygwin] Cygwin: AF_INET and AF_LOCAL: recv_internal: fix MSG_WAITALL support Date: Fri, 23 Oct 2020 12:23:57 +0000 (GMT) [thread overview] Message-ID: <20201023122357.92EE4386F02D@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=3752ab804bda1cbb38b5da91db8cf14f8bdefa2f commit 3752ab804bda1cbb38b5da91db8cf14f8bdefa2f Author: Ken Brown via Cygwin-patches <cygwin-patches@cygwin.com> Date: Mon Oct 12 14:02:13 2020 -0400 Cygwin: AF_INET and AF_LOCAL: recv_internal: fix MSG_WAITALL support If MSG_WAITALL is set, recv_internal calls WSARecv or WSARecvFrom in a loop, in an effort to fill all the scatter-gather buffers. The test for whether all the buffers are full was previously incorrect.
