On AIX, you might want to open the files using O_DSYNC flag: (see)
http://publibn.boulder.ibm.com/doc_link/en_US/a_doc_lib/libs/basetrf1/open.htm#HDRA1509805
Test results:
Opening for rdonly
kwrite(1, 0xF0373B18, 19) = 19
open("/home/ixion/T", O_RDONLY|O_LARGEFILE) = 3
fsync(3) Err#9 EBADF
close(3) = 0
Opening for rdw
kwrite(1, 0xF0373B18, 16) = 16
open("/home/ixion/T", O_RDWR|O_LARGEFILE) Err#21 EISDIR
close(-1) Err#9 EBADF
kfcntl(1, F_GETFL, 0x20000BC8) = 2
kfcntl(2, F_GETFL, 0xF0373B18) = 2
Dan,
If you want any other quick tests cases run, let me know and I'll put them
together.
Thanks,
Ken

I'll test this with a quick bit of C code and get back to you with the truss

Good catch Roger! ( and thanks)

Ah... Quite possibly. In os_unix.c directories are opened with:
fd = open(zDirname, O_RDONLY|O_BINARY, 0);
