Re: [libvirt] [PATCH 2/6] Add public APIs for storage volume upload/download

New APIs are added allowing streaming of content to/from storage volumes. * include/libvirt/libvirt.h.in: Add virStorageVolUpload and virStorageVolDownload APIs * src/driver.h, src/libvirt.c, src/libvirt_public.syms: Stub code for new APIs * src/storage/storage_driver.c, src/esx/esx_storage_driver.c: Add dummy entries in driver table for new APIs --- include/libvirt/libvirt.h.in | 10 +++ include/libvirt/virterror.h | 1 + src/driver.h | 14 ++++ src/esx/esx_storage_driver.c | 2 + src/libvirt.c | 140 ++++++++++++++++++++++++++++++++++++++++++ src/libvirt_public.syms | 2 + src/storage/storage_driver.c | 2 + src/util/virterror.c | 6 ++ 8 files changed, 177 insertions(+), 0 deletions(-)
