| 12 | of strings specified by <em class="parameter"><code>string</code></em>. Any |
| 13 | source code previously stored in the shader object is completely |
| 14 | replaced. The number of strings in the array is specified by |
| 15 | <em class="parameter"><code>count</code></em>. If <em class="parameter"><code>length</code></em> |
| 16 | is <code class="constant">NULL</code>, each string is assumed to be null |
| 17 | terminated. If <em class="parameter"><code>length</code></em> is a value other |
| 18 | than <code class="constant">NULL</code>, it points to an array containing |
| 19 | a string length for each of the corresponding elements of |
| 20 | <em class="parameter"><code>string</code></em>. Each element in the |
| 21 | <em class="parameter"><code>length</code></em> array may contain the length of |
| 22 | the corresponding string (the null character is not counted as |
| 23 | part of the string length) or a value less than 0 to indicate |
| 24 | that the string is null terminated. The source code strings are |
| 25 | not scanned or parsed at this time; they are simply copied into |
