11 | <code class="function">glUseProgramStages</code> binds executables from a program object | |
12 | associated with a specified set of shader stages to the program pipeline object given | |
13 | by <em class="parameter"><code>pipeline</code></em>. | |
14 | <em class="parameter"><code>pipeline</code></em> specifies the program pipeline object to which to bind | |
15 | the executables. <em class="parameter"><code>stages</code></em> contains a logical combination of bits | |
16 | indicating the shader stages to use within <em class="parameter"><code>program</code></em> with the program | |
17 | pipeline object <em class="parameter"><code>pipeline</code></em>. <em class="parameter"><code>stages</code></em> must be | |
18 | a logical combination of <code class="constant">GL_VERTEX_SHADER_BIT</code>, | |
19 | <code class="constant">GL_TESS_CONTROL_SHADER_BIT</code>, <code class="constant">GL_TESS_EVALUATION_SHADER_BIT</code>, | |
20 | <code class="constant">GL_GEOMETRY_SHADER_BIT</code>, <code class="constant">GL_FRAGMENT_SHADER_BIT</code> and <code class="constant">GL_COMPUTE_SHADER_BIT</code>. | |
21 | Additionally, the special value <code class="constant">GL_ALL_SHADER_BITS</code> may be specified to | |
22 | indicate that all executables contained in <em class="parameter"><code>program</code></em> should be | |
23 | installed in <em class="parameter"><code>pipeline</code></em>. | |
24 | </p><p> | |
25 | If <em class="parameter"><code>program</code></em> refers to a program object with a valid shader attached for | |
26 | an indicated shader stage, <code class="function">glUseProgramStages</code> installs the executable | |
27 | code for that stage in the indicated program pipeline object <em class="parameter"><code>pipeline</code></em>. | |
28 | If <em class="parameter"><code>program</code></em> is zero, or refers to a program object with no valid shader | |
29 | executable for a given stage, it is as if the pipeline object has no programmable stage configured | |
30 | for the indicated shader stages. If <em class="parameter"><code>stages</code></em> contains bits other than those | |
31 | listed above, and is not equal to <code class="constant">GL_ALL_SHADER_BITS</code>, an error is generated. | |
32 | </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="notes"></a><h2>Notes</h2><p> | |
33 | The <code class="constant">GL_COMPUTE_SHADER_BIT</code> bit is available only if the GL version is 4.3 or greater. | |
34 | </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="errors"></a><h2>Errors</h2><p> | |
35 | <code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>shaders</code></em> contains | |
36 | set bits that are not recognized, and is not the reserved value <code class="constant">GL_ALL_SHADER_BITS</code>. | |
37 | </p><p> | |
38 | <code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>program</code></em> refers | |
39 | to a program object that was not linked with its <code class="constant">GL_PROGRAM_SEPARABLE</code> status set. | |
40 | </p><p> | |
41 | <code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>program</code></em> refers | |
42 | to a program object that has not been successfully linked. | |
43 | </p><p> | |
44 | <code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>pipeline</code></em> is not | |
