* dd: fix handling of 'conv=notrunc seek=N'Ron Yorston2020-05-201-3/+22
| | | | | | | | | | | | | | | | | | Commit e6680912a (dd: create a sparse file when seek=N is used) broke the use of 'conv=notrunc seek=N' to modify existing files. Rename seek_sparse() to make_sparse() and: - add an argument to specify the start of the sparse region; - call make_sparse() before ftruncate(); - call make_sparse() only if: * we can determine the size of the file; * the file is not open in append mode; * the file is being extended. This should fix GitHub issue #186.
* dd: create a sparse file when seek=N is usedRon Yorston2020-03-241-0/+3
| | | | | | | When the seek=N argument is used mark the file as sparse and set the range that is sparse. See https://stackoverflow.com/questions/4011508/how-to-create-a-sparse-file-on-ntfs

* | win32: restrict visibility of special devicesRon Yorston2018-03-151-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling of the special devices /dev/zero and /dev/urandom was inconsistent: - they could be used as arguments to 'cat' but not 'od'; - they could not be used in shell redirection. Restrict the use of these devices to two places: - as input files to 'dd' with the 'if=' argument; - internally within 'shred'. See GitHub issue #98.

* | dd: silence warning on 64-bit systemsRon Yorston2017-08-311-3/+3
| | | | | | | | | | | | | | | | | | | | | | On 64-bit systems size_t may be larger than unsigned long, resulting in a warning when -1L is cast to size_t. There's little to be gained from allowing obs and ibs take values larger than will fit in a signed long as the subsequent malloc will probably fail. Limit their range to ULONG_MAX/2.
