| 7 | <code class="function">glValidateProgramPipeline</code> instructs the implementation to validate the | |
| 8 | shader executables contained in <em class="parameter"><code>pipeline</code></em> against the current GL state. | |
| 9 | The implementation may use this as an opportunity to perform any internal shader modifications | |
| 10 | that may be required to ensure correct operation of the installed shaders given the | |
| 11 | current GL state. | |
| 12 | </p><p> | |
| 13 | After a program pipeline has been validated, its validation status is set to <code class="constant">GL_TRUE</code>. | |
| 14 | The validation status of a program pipeline object may be queried by calling | |
| 15 | <a href="glGetProgramPipeline.xml"><span class="citerefentry"><span class="refentrytitle">glGetProgramPipeline</span></span></a> with | |
| 16 | parameter <code class="constant">GL_VALIDATE_STATUS</code>. | |
| 17 | </p><p> | |
| 18 | If <em class="parameter"><code>pipeline</code></em> is a name previously returned from a call to | |
| 19 | <a href="glGenProgramPipelines.xml"><span class="citerefentry"><span class="refentrytitle">glGenProgramPipelines</span></span></a> but | |
| 20 | that has not yet been bound by a call to <a href="glBindProgramPipeline.xml"><span class="citerefentry"><span class="refentrytitle">glBindProgramPipeline</span></span></a>, | |
| 21 | a new program pipeline object is created with name <em class="parameter"><code>pipeline</code></em> and | |
| 22 | the default state vector. | |
| 23 | </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="errors"></a><h2>Errors</h2><p> | |
| 24 | <code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>pipeline</code></em> is not | |
| 25 | a name previously returned from a call to <a href="glGenProgramPipelines.xml"><span class="citerefentry"><span class="refentrytitle">glGenProgramPipelines</span></span></a> | |
| 26 | or if such a name has been deleted by a call to | |
