I would like to write a few programs to lay out our large databases onto a DAT tape. Unfortunately, I lack all expertise with tape drives, and my Wang manual is less than explicit. I understand how to use devices (/dev/rxt0, /dev/nrxt0) to read and write data byte by byte and file by file. What I really would like, though, is the additional ability to keep an index on disk, and do a fast fseek() that employs the WangDATs fast seek facilities. How would I do this in a C program? I.e. could some kind sole please send me replacements for fseek() and ftell() with such DAT tape drives, please? Thanks for any information. /ivo welch PS: Has anyone used SafetyNet? It got a rave review, but my efforts to contact the author has been unsuccessful.
