New Revision: 298901
URL: https://svnweb.freebsd.org/changeset/base/298901
Log:
restore: promote some getfiles() parameters to size_t.
This is based on a change from OpenBSD:
"Fix restore so that it can actually restore files larger than 4GB by
changing the type of "size" to off_t in getfiles() plus little dependent
type cleanup, from Daniel Lucq."
It is an important for machines with 32 bit longs.
While here unsign the flags, also from OpenBSD.
