Hello,
thank you for the answer.
I couldn't understand much from syntactic_callgraph.
But following your last advice: if I find the function by name and then
look at its declaration (*fundec) *and finally list of all statements in
the function (*sallstmts*), how can I tell which statement is a function
call?

Best,
Ivan
