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>.
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.

33 The

39 to a program object that was not linked with its
<code class=

41 <code class=

42 to a program object that has not been successfully linked.
44 <code class=
