| H A D | qemu-file.c | 9504fb51 Thu Nov 05 18:10:35 GMT 2015 Dr. David Alan Gilbert <dgilbert@redhat.com> Add qemu_get_buffer_in_place to avoid copies some of the time
qemu_get_buffer always copies the data it reads to a users buffer,
however in many cases the file buffer inside qemu_file could be given
back to the caller, avoiding the copy. This isn't always possible
depending on the size and alignment of the data.
Thus 'qemu_get_buffer_in_place' either copies the data to a supplied
buffer or updates a pointer to the internal buffer if convenient.
