From 96f47b0d2c307173e0a545ea230e21f1ce8d3fa2 Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Sat, 22 Sep 2012 21:13:28 +0200 Subject: [PATCH] net/socket: Fix compiler warning (regression for MinGW) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 213fd5087e2e4e2da10ad266df0ba950cf7618bf removed a type cast which is needed for MinGW: net/socket.c:136: warning: pointer targets in passing argument 2 of ‘sendto’ differ in signedness /usr/lib/gcc/amd64-mingw32msvc/4.4.4/../../../../amd64-mingw32msvc/include/winsock2.h:1313: note: expected ‘const char *’ but argument is of type ‘const uint8_t *’ Add a 'qemu_sendto' macro which provides that type cast where needed and use the new macro instead of 'sendto'.
