23 | <em class="parameter"><code>label</code></em> is the address of a string that will be used to label an object. | |

26 | <em class="parameter"><code>label</code></em> contains a null-terminated string. If <em class="parameter"><code>label</code></em> | |
27 | is NULL, any debug label is effectively removed from the object. | |
