Call lseek() at the start if output is appending, so that future lseek()s are relative to the right position, fixing the issue with incorrect truncation size (#45).

Only call ftruncate() once, when the output file descriptor is closed at the end, instead of after every lseek() - this corrects the file growth on XFS but has the side effect that writing to stdout in >> (append) mode truncates the file to the wrong size (#45).

For sparse output, instead of fstat(), ftruncate(), then lseek(), do lseek() then ftruncate(), like dd does (#45).

Move the pv__transfer_write_completed label, jumped to on a sparse write, outside of the compound statement; and so, move all of the variables within that compound statement to the start of the function. The GCC on RHEL derivatives like AlmaLinux 9, Rocky 8, CentOS 7/6/5 throws an error if the label is at the end of that block rather than just outside it (#45).
