- Dear Mr. Ward,
-
- Data Exchange Format
-
-
- I've just received the last C User's Journal. As I could
- see in the letters coloumn, you have some first candidates for
- the exchange format library programs.
-
- This brings me to send you this packet: It contains the
- first draft of my version of such an utility. It is mostly
- written according to my draft format description I've send you
- some time ago. As such it includes some features that make the
- format more portable than a plain cpio or tar implementation.
- This features include e. g. the ability to do tab expansion and
- filename conversion. Note that most of the extensions are
- optional and disabled unless actived by a command line switch.
-
- Although it doesn't implement a plain cpio format, the
- utility is able to read 4and5 4write5 cpio disks. So you are able to
- use it with Unix disks you've gotten from anyone.
-
- The program is not a very, very simple one but it uses only
- standard C and should compile under most compiler/operating
- system pairs. It has been developed under Unix (pcc) and passed
- a short test under the following environments: MS-DOS (MSC5.0),
- MS-DOS (Turbo-C1.5), MS-DOS(Lattice-C3.00),
- MS-DOS(Datalight-C2.23to3.11), Starsys (native-compiler).
-
- Note that the program is not really complete today. I only
- send this version so that you can take it into consideration
- when prooving exchange format utilities. There is also GEnoHF new
- documentation included on the disk. Please look at the source
- module for further details.
-
- The loader utilities haven't been upgraded since my last
- letter. This will be done in the near future. They will receive
- a different user interface (but still command line).
-
- The enclosed disk contains my whole development directory
- (except binaries) at its current state. The program I was
- talking about is cugcpio.c. It needs the header file environ.h
- to set the correct execution environment conviguration. No other
- files are required.
-
- At last a request: please give me a little feedback about
-
-
-
- my contribution and how do you think it will fit in the exchange
- format. This keeps me on the right way and perhaps helps me
- saving time if you think it's better to cancel my development.
-
-
-
- Sincerely yours,
-
