Hi all,
Greetings from me!
I am trying the following simple script on FreeBSD 11:
#!/usr/sbin/dtrace -s
syscall::write:entry
/pid == $1/
{
}
and get following error:
# ./tracewrite.d
dtrace: failed to compile script ./tracewrite.d: line 4: macro
argument $1 is not defined
>From this

it seems FreeBSD doesn't support macro argument, right? If I want to
use it, what is the correct method?
Thanks very much in advance!
Best Regards
Nan Xiao
