pid$target:library::entry
{
@a[usym(ucaller),probefunc] = count();
@b[usym(ucaller),probefunc] = min(timestamp);
}
If you're worried about multiple threads of execution, then:
pid$target:library::entry
{
@a[usym(ucaller),probefunc] = count();
@b[tid, usym(ucaller),probefunc] = min(timestamp);
}
will separate them out.
