Backtracing the current thread

To backtrace the currently running process and thread, you can do one of the following:

• Use the BT_PROCESS accessor flag, as described in “Backtracing a thread in another process,” but specify the current pid and tid.
• Use the BT_THREAD accessor flag and select the currently running thread.
• Use the BT_SELF accessor flag. This is the best way to insure that the currently active thread is backtraced:

  if (bt_init_accessor(&acc, BT_SELF) == -1)
  {
    fprintf( stderr, "%s:%i %s (%i)%s\n", __FUNCTION__, __LINE__,
             "bt_init_accessor", errno, strerror(errno));
    return -1;
  }
    

You can also use a preinitialized accessor called bt_acc_self.
