MFC: Allow negative seek offsets for files that can be seeked upon.2001-01-23T14:23:55ZJeroen Ruigrok van der Wervenasmodai@FreeBSD.org2001-01-23T14:23:55Zurn:sha1:ca7db76922583ac75cc0e96e66ff2d2361736c01MFC:2000-08-07T08:30:17ZPaul Saabps@FreeBSD.org2000-08-07T08:30:17Zurn:sha1:ef5163f07aa7e576e96c905c1b82293f7796faa6

Various cleanups are made to reduce warnings. Check return value
of ftruncate() and die on failure.
dd.c 1.28
Fix ``dd if=/dev/zero of=/dev/daN'' on the Alpha by allowing the
label to be overwritten.
dd.c 1.30
Make the comment regarding ftruncate() correct.
Make count=0 set cpy_cnt to -1, which is slight overloading, but makes1999-09-16T19:50:59ZBrian Feldmangreen@FreeBSD.org1999-09-16T19:50:59Zurn:sha1:5ff6541e7a8bf367578694b461f3c49ee5ae8acb
what I was trying to do work much better (ie at all. I could have sworn
it was working...) Fix a SEEK_SET to be SEEK_CUR, and make Bruce's
lseek() test work correctly.
Even more dd(1) cleanups! Thanks to Bruce for staying on my case until1999-09-13T21:47:10ZBrian Feldmangreen@FreeBSD.org1999-09-13T21:47:10Zurn:sha1:7599187e0d5b76d5efebde542f0d862969c2f2b5

ISDISK -> ISSEEK1999-09-12T18:56:12ZBrian Feldmangreen@FreeBSD.org1999-09-12T18:56:12Zurn:sha1:32952d4b37e2af9ee818481aff41144e05fa74ae
Allow a device type of D_DISK or D_MEM to be ISSEEK.
Even more cleanups to dd(1). This is probably the culmination of the1999-09-12T16:51:53ZBrian Feldmangreen@FreeBSD.org1999-09-12T16:51:53Zurn:sha1:58687472541a7cd52def066244dc820419270434
BDEification process of dd(1). Most of the changes are from BDE's archive.
Support for negative offsets is gone again, but the case where you
lseek() onto byte -1 of something from a negative offset using seek/skip
is fixed; if you end up on -1, you won't get a false positive lseek failure.
The biggest changes are to data types (more size_t, for instance) and
argument parsing. skip/seek on /dev/{,k}mem now occurs (instead of "read
until you reach the offset") due to mem devices now being D_DISK. Some
const things are now correctly declared as such, and the "case table"
building is better. The only thing that seems to be left to make dd(1)
everything TOG wants it to be is l10n.
Make a bit more headway with dd's argument parsing, etc. get_bsz() is1999-09-11T00:02:42ZBrian Feldmangreen@FreeBSD.org1999-09-11T00:02:42Zurn:sha1:e14f7e789a25e6c026475b00d911ea8727e05ba8
renamed get_num() since it's not just about block sizes. skip and
seek can be any offset, including negative, now. Some style bogons are fixed.

Also, fix pos_out() to do the same checks pos_in() did.
Done for: jdp, luigi, the good of the world
