Path: uunet!rs From: rs@uunet.UU.NET (Rich Salz) Newsgroups: comp.sources.unix Subject: v10i088: Magtape handling package, Part01/02 Message-ID: <759@uunet.UU.NET> Date: 3 Aug 87 21:23:55 GMT Organization: UUNET Communications Services, Arlington, VA Lines: 1799 Approved: rs@uunet.UU.NET Submitted-by: Dick Grune <dick@cs.vu.nl> Posting-number: Volume 10, Issue 88 Archive-name: magtapetools/Part01 David Hayes' posting of his ansitape program reminded me of my more general (but less specialized) magtape handling package, which has been in use for quite some years and which I have, in the course of time, sent out to some number of people. I also sent it, some years ago, to net.sources. It does not show up in your last listing of mod.sources. Anyway, it has been updated and adjusted, e.g., for machines with funny byte order. This letter begins with a very short comparison of his program to my package, followed by part 1 of 2 of the sources (sharchive).

X# Written by Dick Grune, Vrije Universiteit, Amsterdam. X# X XSALES TALK X If you have one or more magtape units and want to do more with Xthem than just run `tar', this is for you. X X On the shell level this package offers programs for X - getting a quick look at a tape, X - making exact copies of tapes even if you've got only one magtape unit, X - extracting arbitrary portions from tapes and X - the reading and writing of ANSI standard labelled tapes. XAll these programs work equally well on real tapes and on tape images Xon disk. X X On the C-level it supplies routines for handling real tapes and Xtape images on disk as a unified concept (`generalized magtape'). X X XINSTALLATION X- Take a look at the file `tploc.h' which requires you to define: X X SYSCODE the name of your installation X DEV_LOW, DEV_NORMAL, DEV_HIGH the name(s) of the magtape unit(s) X X You may also #define one of the following flags to describe X the reading and writing of the tape: X NORMAL (default) anything goes (VAX, etc) X EVEN only even blocksize allowed (PDP11) X SWAB bytes must be swapped (M68000) X X If you are not on a UNIX(like) system, you may look at `sys.c', X which contains the (non-magtape) interface to the OS. X X- Call `make all' and the shell commands as described in mag(1) X will appear. X X- To install the shell commands, change the macro USR (and possibly X BIN, LIB, and INC) in the `makefile' and do `make install'. To X install the C-routine library `libt.a', do `make libt'. X X- Now do X X ansir -fp test.image X X to get a feel for what it does. (Then do it a second time!). X XCYBER X If you happen to have a Control Data Cyber around, running XSCOPE or NOS/BE, call `make NOS' to get `NOSsplit', a program for Xreading Cyber SI-format tapes, and `NOStr' which converts from various XCyber character codes.

X.\" Written by Dick Grune, Vrije Universiteit, Amsterdam. X.\" X.TH MAG 3 83/06/23 X.SH NAME Xmag \- implement generalized magtape X.SH SYNOPSIS X.PP X.B "#include <tp.h>" X.PP X.B "TPFILE *tpopen(unit, nmdns, rwx) char *nmdns, *rwx;" X.PP X.B "tpclose(tf) TPFILE *tf;" X.PP X.B "int tpread(tf, buf, size) TPFILE *tf; char *buf;" X.PP X.B "tpwrite(tf, buf, size) TPFILE *tf; char *buf;" X.PP X.B "tperrout(stream) FILE *stream;" X.SH DESCRIPTION XThese routines implement the generalized magtape described in X.IR mag (I). XSuch a generalized magtape is viewed as a sequence of blocks each of which Xis written and read in one piece. A tape mark is represented as a block of Xlength 0. The blocks correspond to physical blocks on tape (as separated Xby Interrecord Gaps). On a tape image each block is preceded by its length Xin format "%08d". X.PP XA generalized magtape is handled by these routines as a pointer to a XTPFILE. Such a pointer is obtained from X.IR tpopen . XThe X.I unit Xand the X.I nmdns Xdescribe the generalized magtape; these are the possibilities: X.PP Xa real magtape: X.I unit Xis a small non-negative integer (the unit number); X.I nmdns Xis TP_DENL, TP_DENN or TP_DENH (for low, normal or high density). X.PP Xa tape image: X.I unit Xis TP_IMAG; X.I nmdns Xis the file name. X.PP Xa character device: X.I unit Xis TP_CDEV; X.I nmdns Xis the device name. X.PP XThe third parameter X.I rwx Xis either "r" or "rx" for reading or "w" for writing; "rx" suppresses Xthe recognition of end-of-file in real magtapes (see X.IR tpread ). X.PP X.I Tpclose Xcloses a generalized magtape; this causes a rewind and makes room for Xother such files, since only a limited number (specified in _TP_MOPEN) Xcan be open at the same time. X.PP X.I Tpread Xreads one block into X.I buf Xto a maximum of X.I size Xcharacters. The rest of the block, if present, is skipped. XIt returns the number of Xcharacters read, or 0 for a tape mark, or -1 for an end-of-file. XOn a tape image file the end-of-file coincides with the actual end-of-file. XOn a real magtape or on a character device three conditions can cause Xan end-of-file: X.IP X4 consecutive tape marks, X.br X2 consecutive read errors, or X.br X1 read error preceded by a tape mark, X.PP Xunless "rx" was specified in the call of X.IR tpopen , Xin which case only 100 consecutive read errors will cause an end-of-file X(to prevent the program from looping on end-of-reel). X.PP X.I Tpwrite Xwrites one block from X.I buf Xif X.I size X> 0, or a tape mark if X.I size X= 0. X.SH DIAGNOSTICS XIf an error condition (other than end-of-file) is found, a message is Xprinted on X.I stderr Xand the program exits. This default can be changed by calling X.I tperrout.
