i got a function which is called by many others, now i want to
know who the callers are at runtime. How can I do this in C++, say
print out the caller functions names? thanks.

gprof cannot profile kernel, i used oprof but there's no call graph, sigh.

Many peformance tools (profiler) can do this. For example, gprof from GNU,
Vtune from Intel, and Sun's Performance Analyzer. Check their manual for usage
.
You problem seems to be a typical call-graph profiling problem. C++ may be
tricky because the function names might be changed by compilers to some
strange ones.
