Bcc: probe of c++ function

[axot]

How to trace a c++ function like a::b::c in trace.py ?

[goldshtn]

You need to use the mangled name of the function. I usually run objdump -tT myfile to find the desired symbol name.

Alternatively, defined a USDT Tracepoint in the function for more stable probe and better experience.

Thank you, mangled name works. Using USDT Tracepoint may a easy way for debugging!
