From 63dfbd7ee03185c181a0791958ec9c8337089b55 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 22 Feb 2013 17:36:16 +0100 Subject: migration: use qemu_file_set_error Remove the return value of buffered_flush, pass it via the error code of s->file. Once this is done, the error can be retrieved simply via migrate_fd_close's call to qemu_fclose.
