I'm a complete novice with dtrace - never used it before.
I cut and pasted your script and then made the assumption
that the printf statement goes on a single line. I get an error:
[t43p:/home/stu/temp/dtrace]# ./cd_eject
dtrace: failed to compile script ./cd_eject: line 5: syntax error near ")"
[t43p:/home/stu/temp/dtrace]# [t43p:/home/stu/temp/dtrace]# cat cd_eject
#!/usr/sbin/dtrace -s
fbt::scsa1394_cmd_fake_comp:entry
{
self->sp = (scsa1394_state_t *)arg0;
self->cmd = (scsa1394_cmd_t *)arg1;
self->lp = self->cmd->sc_lun;
printf("l_rmb_orig %d, l_nosup_tur %d, l_nosup_start_stop %d, l_nosup_inquiry
%d", self->lp->l_rmb_orig, self->lp->l_nosup_tur, self->lp->l_nosup_start_stop,
self->lp->l_nosup_inquiry);
}
[t43p:/home/stu/temp/dtrace]#
Suggestions on what I'm doing wrong? Is the error in
the line:
self->sp = (scsa1394_state_t *)arg0;
Thanks,
Stuart
