Brian Feldman dd92370286 I've been Brucified! I did evil things with typedefs, but I'll do it
the correct (but less aesthetic) way, now.  New lesson: correctness
and aestheticity may be mutually exclusive at times.

Brian Feldman 67f80d12af Do proper constification in args.c. This shuts up -Wcast-qual (thanks,
bfumerola for that pointer!) in GCC complaining about losing a const.

While I'm here, might as well mark in the Makefile that I'm the
${MAINTAINER}.  It seems like that's what everyone's doing these days.

Brian Feldman 5ff6541e7a Make count=0 set cpy_cnt to -1, which is slight overloading, but makes
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.

Brian Feldman 1838cf5671 Let count=-something fail, while count=0 may succeed, thus making dd(1)
useful as a seeking-tool as well as its many other uses.  Previously,
dd(1) would succeed with count=0, but wouldn't get to the point that
blocks were to be read/written. This is a more useful behavior, and
this specific case doesn't seem to be handled by POSIX.

Brian Feldman 7599187e0d Even more dd(1) cleanups! Thanks to Bruce for staying on my case until
we're done (not yet!) :)

Brian Feldman 5868747254 Even more cleanups to dd(1). This is probably the culmination of the
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.

Brian Feldman e14f7e789a Make a bit more headway with dd's argument parsing, etc. get_bsz() is
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.

Peter Wemm 2a4562393f $Id$ -> $FreeBSD$ 1999-08-27 23:15:48 +00:00
Brian Feldman 54946e00b2 This is the second round of dd(1) changes. Some changes made/reversed by
request of Bruce. More changes may follow later. 'g' multiplier has
been added (i.e. dd seek=5g if=bigfile.) Some minor corrections were made
as well.

Brian Feldman 767bc8ad79 Miscellaneous dd(1) changes: mainly fixing variable types (size_t, ssize_t,
off_t, int, u_int64_t, etc.). dd(1) should now work properly with REALLY
big amounts of data.

Joerg Wunsch 1898febe2d Sort "sparse" into alphabetical order, since dd's `conv' options need
to be sorted.  This temporarily broke the "osync" option.
1997-11-11 20:35:29 +00:00
Joerg Wunsch 4ddfeabd8f Teach dd(1) about an option to write sparse files. Can be useful for
things like diskless clients' swap files etc.

Jordan K. Hubbard 1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

Poul-Henning Kamp ad66f7ee71 Bruce says: "You have been programming in the kernel for too long :-)."
and he's right ... I forgot about this floating point stuff you can
use in user-land :-)

Increase precision of duration to microseconds.
No heuristics to avoid overflow in calculation needed - just depend
on DBL_MAX being a bit larger than LONG_MAX.

Use double instead of `struct timeval' in dd.h so that everything
doesn't have to include <sys/time.h>.

Fixed style bugs in recent and old FreeBSD changes.
