Writer subclass to write a single Unix file. You must subclass this and implement several virtual functions to write pieces of a file. This takes care of opening and closing the file.

|
protected |
Open the output file. This file is created with a temporary name so that the original file is not replaced until the write is successful. This returns false and calls iop->error() if it can't open the file.
References DD::Image::Op::critical(), file, DD::Image::Writer::filename(), getTempFileName(), DD::Image::Writer::iop, and offset.
|
protected |
Close the output file. If there have not been any errors this will mv the temporary file to the correct place.
References DD::Image::Writer::aborted(), DD::Image::Op::critical(), file, DD::Image::Writer::filename(), getTempFileName(), and DD::Image::Writer::iop.
|
protected |
Write length bytes to the file. Call iop->error() on any errors and returns false. Returns true on success.

protected |
|
protected |
Move the write pointer to offset. This is done efficiently if the pointer is already at that point. Calls iop->error() on any errors and returns false. Returns true on success.

inlineprotected |
Returns where the pointer currently is.
|
protected |
Returns a temporary file name for the current output file (e. g. filename.ext.tmp)
Returns a temporary file name for the given actual file name. e. g. filename.ext -> filename.ext.tmp Pass in NULL to use the current filename().
