DTraceToolkit has a dtrace script (Proc/pidpersec.d) that refers to a variable mpid as below
profile:::tick-1sec
{
printf("%-22Y %8d %6d\n", walltimestamp, `mpid, pids);
pids = 0;
}
Where is `mpid getting picked from (it isn't declared anywhere else)?
What does the character ` in `mpid signify?
I do not see any reference to this variable in the dtrace manual/user-guide.
