Re: [TUHS] 1st Edition UNIX syscalls

A while back I wrote about the system calls in 1st Edition UNIX. I was idly wondering how much of 1st Ed (and prior) still existed in modern UNIXes. Obviously, with the change of language from assembly to C, we won't be able to find identical lines, but the enumeration of system calls, for example, is one way to spot the lineage: 1st Edition Open Solaris [1] ============================== V1_RELE 0 indir V1_EXIT 1 rexit V1_FORK 2 forkall V1_READ 3 read V1_WRITE 4 write V1_OPEN 5 open V1_CLOSE 6 close V1_WAIT 7 wait V1_CREAT 8 creat V1_LINK 9 link V1_UNLINK 10 unlink V1_EXEC 11 exec V1_CHDIR 12 chdir V1_TIME 13 gtime V1_MKDIR 14 mknod V1_CHMOD 15 chmod V1_CHOWN 16 chown V1_BREAK 17 brk V1_STAT 18 stat V1_SEEK 19 lseek32 or lseek64 V1_TELL 20 getpid V1_MOUNT 21 mount V1_UMOUNT 22 umount V1_SETUID 23 setuid V1_GETUID 24 getuid V1_STIME 25 stime V1_QUIT 26 pcsample V1_INTR 27 alarm V1_FSTAT 28 fstat V1_CEMT 29 pause V1_SMDATE 30 utime V1_STTY 31 stty V1_GTTY 32 gtty V1_ILGINS 33 access Quite a surprising similarity after nearly 4 decades.
