From a202a4c001fd35b50d99abcc329bc9e666eb8eed Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Thu, 13 Aug 2015 11:51:33 +0100 Subject: migration: size_t'ify some of qemu-file This is a start on using size_t more in qemu-file and friends; it fixes up QEMUFilePutBufferFunc and QEMUFileGetBufferFunc to take size_t lengths and return ssize_t return values (like read(2)) and fixes up all the different implementations of them. Note that I've not yet followed this deeply into bdrv_ implementations.
