</h2><p><code class=
"function">glShaderSource
</code> sets the source code
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.
