13 | <code class="function">glGetObjectPtrLabel</code> retrieves the label of the sync object identified by | |
14 | <em class="parameter"><code>ptr</code></em>. | |
15 | </p><p> | |
16 | <em class="parameter"><code>label</code></em> is the address of a string that will be used to store the object label. | |
17 | <em class="parameter"><code>bufSize</code></em> specifies the number of characters in the array identified by <em class="parameter"><code>label</code></em>. | |
18 | <em class="parameter"><code>length</code></em> contains the address of a variable which will receive the the number of characters in the object label. | |
19 | If <em class="parameter"><code>length</code></em> is NULL, then it is ignored and no data is written. Likewise, if <em class="parameter"><code>label</code></em> | |
20 | is NULL, or if <em class="parameter"><code>bufSize</code></em> is zero then no data is written to <em class="parameter"><code>label</code></em>. | |
