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