* MFC rev. 265593:thomas2014-05-211-24/+43
| | | | | | | | | (dd_out): Fix handling of all-zeroes block at end of input with conv=sparse. PR: bin/189174 PR: bin/189284 Reviewed by: kib
* MFC r264059+264067:delphij2014-04-174-32/+67
| | | | | | | | | | | | Implement GNU's extension of 'status' operand. The GNU syntax is borrowed where syntax status=noxfer means no transfer statistics and status=none means no status information at all. This feature is useful because the statistics information can sometimes be annoying, and redirecting stderr to /dev/null would mean error messages also gets silenced. Obtained from: OpenBSD

* Literally follow POSIX:kib2013-04-231-1/+1
| | | | | | | | | | | | | If the bs= expr operand is specified and no conversions other than sync, noerror, or notrunc are requested, the data returned from each input block shall be written as a separate output block. In particular, when both bs=size and conv=sparce were specified, the resulted file was fully filled, instead of sparce.

* IFP4 change 222074.brooks2013-04-031-0/+7
| | | | | | | | | | Introduce an explicit close of the output descriptor so that work done on close is accounted for in the summary output triggered at exit (implicit close()s occur after atexit() hooks). This is useful because some devices such as cfi(4) may perform signficant work after a close occurs (e.g. erasing and rewriting a block of flash).
* More -Wmissing-variable-declarations fixes.ed2012-10-201-0/+5
| | | | | | | | | | In addition to adding missing `static' keywords: - bin/dd: Pull in `extern.h' to guarantee consistency with source file. - libexec/rpc.rusersd: Move shared globals into an extern.h. - libexec/talkd: Move `debug' and `hostname' into extern.h. - usr.bin/cksum: Put counters in extern.h, as they are used by ckdist/mtree. - usr.bin/m4: Move `end_result' into extern.h. - usr.sbin/services_mkdb: Move shared globals into an extern.h.
* Rework all non-contributed files that use `struct timezone'.ed2012-09-012-3/+3
| | | | | | | | | | | | | | This structure is not part of POSIX. According to POSIX, gettimeofday() has the following prototype: int gettimeofday(struct timeval *restrict tp, void *restrict tzp); Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is not used). Remove dead error handling code. Also use NULL for a nul-pointer instead of integer 0. While there, change all pieces of code that only use tv_sec to use time(3), as this provides less overhead.

* Add an example of using bs=2048 to duplicate data CD-ROMs.keramida2009-01-231-0/+5
| | | | | | | | | | | This should be a bit useful for users who look at the manpage and then try to copy data CD-ROM disks using dd. A lot of us know that bs=2048 is required, but it still manages to cause a bit of grief to those who haven't heard about it.
