Can I call functions in a thread

Hello ALL,


I wonder if it is safe to call a function in a thread, which recursively calls other functions like the following manner.

Code:

---

void thread_func(void*)
{
      ......       
      subfunc_1();
      ......   

}

subfunc_1()
{
    subfunc_11();
}

subfunc_11()
{
    subfunc_111();
}

---

It's safe, you're just altering the instruction flow of the thread.
