dtrace discuss - Apr 2007 - something puzzled in libdtrace source code

Dear all:

I''m reading the dtrace source code now. I found
"NOTE(NOW_INVISIBLE_TO_OTHER_THREADS(*elf));" appears many times when
I came
to the libdtrace part.
The tools I used is source insight, but it could not report any useful
information about "NOW_INVISIBLE_TO_OTHER_THREADS" to me, neither
declaration nor definition of it.

Then I tried to use ggrep command, "ggrep -R -I -n
NOW_INVISIBLE_TO_OTHER_THREADS", but it was only report the usage of it.
e.g. ./cmd/syslogd/syslogd.c:801:
_NOTE(NOW_INVISIBLE_TO_OTHER_THREADS(*mp))

I was puzzled about this. Where was the definition and declaration of
NOW_INVISIBLE_TO_OTHER_THREADS?

Thanks in advance.

Regards
TJ
