15 | <code class="function">glShaderBinary</code> loads pre-compiled shader binary code into the <em class="parameter"><code>count</code></em> | |
16 | shader objects whose handles are given in <em class="parameter"><code>shaders</code></em>. <em class="parameter"><code>binary</code></em> | |
17 | points to <em class="parameter"><code>length</code></em> bytes of binary shader code stored in client memory. | |
18 | <em class="parameter"><code>binaryFormat</code></em> specifies the format of the pre-compiled code. | |
19 | </p><p> | |
20 | The binary image contained in <em class="parameter"><code>binary</code></em> will be decoded according to the extension | |
21 | specification defining the specified <em class="parameter"><code>binaryFormat</code></em> token. OpenGL | |
22 | does not define any specific binary formats, but it does provide a mechanism to obtain token | |
23 | vaues for such formats provided by such extensions. | |
24 | </p><p> | |
25 | Depending on the types of the shader objects in <em class="parameter"><code>shaders</code></em>, <code class="function">glShaderBinary</code> | |
26 | will individually load binary vertex or fragment shaders, or load an executable binary that contains an optimized | |
27 | pair of vertex and fragment shaders stored in the same binary. | |
28 | </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="errors"></a><h2>Errors</h2><p> | |
29 | <code class="constant">GL_INVALID_OPERATION</code> is generated if more than one of the handles in | |
30 | <em class="parameter"><code>shaders</code></em> refers to the same shader object. | |
31 | </p><p> | |
32 | <code class="constant">GL_INVALID_ENUM</code> is generated if <em class="parameter"><code>binaryFormat</code></em> is not an | |
33 | accepted value. | |
34 | </p><p> | |
35 | <code class="constant">GL_INVALID_VALUE</code> is generated if the data pointed to by <em class="parameter"><code>binary</code></em> | |
36 | does not match the format specified by <em class="parameter"><code>binaryFormat</code></em>. | |
