Inheritance¶

Description¶

TDosStream is a stream that stores it's contents in a file. it overrides a couple of methods of TStream for this.

In addition to the fields inherited from TStream (see TStream), there are some extra fields, that describe the file. (mainly the name and the OS file handle)

No buffering in memory is done when using TDosStream. All data are written directly to the file. For a stream that buffers in memory, see TBufStream.
