How to "alternate" C / C ++ with my string (only inside functions in appropriate places)?

Question

For example, there is a source:

void func1() {
    func3();
    if(qqq) {
         func2();
    }
    func4(
    );
}

It should be converted to:

void func1() {
MYMACRO
    func3();
MYMACRO
    if(qqq) {
MYMACRO
         func2();
MYMACRO
    }
MYMACRO
    func4(
    );
MYMACRO
}

those. to insert "MYMACRO \ n" at the end of each line, where the operator can be, only inside functions.

How to do it easily? Should I use regular expressions? What tools should be used?

For example, can gcc output all line numbers from all statements starting (or ending) inside functions?

@related How do I tell gcc to manage code with calls to my own function every _line_ of code?

@related Profiler, which should use _real_ time to measure (including waiting for system calls), spend on this function, not _CPU_ one
