11 | in <em class="parameter"><code>shader</code></em> to the source code in the array | |
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 | |
26 | the specified shader object.</p></div><div class="refsect1" lang="en" xml:lang="en"><a id="notes"></a><h2>Notes</h2><p>OpenGL copies the shader source code strings when | |
