| 10 | shader object and returns a non-zero value by which it can be | |
| 11 | referenced. A shader object is used to maintain the source code | |
| 12 | strings that define a shader. <em class="parameter"><code>shaderType</code></em> | |
| 13 | indicates the type of shader to be created. Five types of shader | |
| 14 | are supported. A shader of type | |
| 15 | <code class="constant">GL_VERTEX_SHADER</code> is a shader that is | |
| 16 | intended to run on the programmable vertex processor. | |
| 17 | A shader of type <code class="constant">GL_TESS_CONTROL_SHADER</code> is a shader that | |
| 18 | is intended to run on the programmable tessellation processor in the control stage. | |
| 19 | A shader of type <code class="constant">GL_TESS_EVALUATION_SHADER</code> is a shader that | |
| 20 | is intended to run on the programmable tessellation processor in the evaluation stage. | |
| 21 | A shader of type | |
| 22 | <code class="constant">GL_GEOMETRY_SHADER</code> is a shader that is intended to | |
| 23 | run on the programmable geometry processor. A shader of | |
| 24 | type <code class="constant">GL_FRAGMENT_SHADER</code> is a shader that is | |
| 25 | intended to run on the programmable fragment processor.</p><p>When created, a shader object's | |
| 26 | <code class="constant">GL_SHADER_TYPE</code> parameter is set to either | |
| 27 | <code class="constant">GL_VERTEX_SHADER</code>, <code class="constant">GL_TESS_CONTROL_SHADER</code>, | |
| 28 | <code class="constant">GL_TESS_EVALUATION_SHADER</code>, <code class="constant">GL_GEOMETRY_SHADER</code> | |
| 29 | or <code class="constant">GL_FRAGMENT_SHADER</code>, depending on the value | |
| 30 | of <em class="parameter"><code>shaderType</code></em>.</p></div><div class="refsect1" lang="en" xml:lang="en"><a id="notes"></a><h2>Notes</h2><p>Like buffer and texture objects, the name space for | |
| 31 | shader objects may be shared across a set of contexts, as long | |
| 32 | as the server sides of the contexts share the same address | |
| 33 | space. If the name space is shared across contexts, any attached | |
| 34 | objects and the data associated with those attached objects are | |
| 35 | shared as well.</p><p>Applications are responsible for providing the | |
| 36 | synchronization across API calls when objects are accessed from | |
| 37 | different execution threads.</p></div><div class="refsect1" lang="en" xml:lang="en"><a id="errors"></a><h2>Errors</h2><p>This function returns 0 if an error occurs creating the | |
