Hi Terry
thanks a lot for your answer
but probably I didn't get it right
here is what I did
I created simple command line tool
#include <iostream>
#include <unistd.h>
using namespace std;
extern "C" {
void test_c() {
cout << "Hello, World! test_cpp" << endl;
}
}
void test_cpp() {
test_c();
}
int main (int argc, char * const argv[]) {
for(int i = 0; i < 100; i++) {
sleep(1);
test_cpp();
}
return 0;
}
nm returns
....T __Z8test_cppv
and
......T _test_c
so I created 2 probs
one for test_c
pid : DTraceCPPFunction : test_c:entry
and another for
.*test_cpp.*
pid : DTraceCPPFunction : .*test_cpp.* : entry
but only prob for test_c did work
and I can clearly see in the stack trace that test_cpp was called
thanks

You can't use a colon in a name, but you can use a regular
expression. You can also add a string compare as one of the
constraints on pthe probe firing (in the /<predicate>/).

Hi, is it possible to trace C++ function?
I was able to create prob for c++ function
::foo_cpp
that was called from c function foo_c
I created 2 probs one for foo_c and another for ::foo_cpp
but I was able to see events only for foo_c prob
(and I can see ::foo_cpp in stack)
and none for ::foo_cpp prob
I think it's wrong, because
foo_c is called ONLY from ::foo_cpp
