Unix 6th edition man macros
On Fri, 10 Mar 2006 02:02:13 -0500 Damn I've sat in front of enough of them - and I never did find out but a quick look...
Exercise complete (though, it depends on sys-endian.h. It could probably be modified to use in-netinet.h or manual reordering - it probably also needs changes where the magic is used). I did this based on ar.c in the 7th edition sources I tried it with the v6 one, but couldn't make it work - since v7's api, and for that matter its C syntax, is much closer to a "modern" unix, it was less effort
ar.h: #ifndef ARH #define ARH #if BYTEORDER == LITTLEENDIAN #define ARMAG INT32C(0x65FF0000) #else #define ARMAG INT32C(0xFF65) #endif struct arhdr { char arname14; int8t aruid; int8t argid; int32t ardate; int32t arsize; int32t armode; } attribute((packed)); #endif

William J. Leary Jr. IIRC, it was a "joke newsgroup" to begin with (possibly contemporaneous with alt.tv.startrek.ensign.crusher.die.die.die era). comp.terminals would certainly be appropriate, and in fact Rick Shuford's...
The" ? Which one is "The" ? I found a number of them, with contradictory statements, or...
Compiled with gcc -fwritable-strings since i didn't feel like fixing its use of mktemp.
