From fdcf6e65bce1f8972030fed7af5e8aa5f6ae92c6 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Sun, 6 Jul 2014 16:43:33 +0800 Subject: [PATCH] qemu-img: Check getchar() return value in read_password() for WIN32 getchar() is a standard c library function which may return with failure (e.g. -1), so like another platforms, also need check it under WIN32. And make the related code match current qemu code styles, too.
