<code class="function">glGetProgramPipelineInfoLog</code> retrieves the info log for the program
pipeline object <em class="parameter"><code>pipeline</code></em>. The info log, including its null terminator,
is written into the array of characters whose address is given by <em class="parameter"><code>infoLog</code></em>.
The maximum number of characters that may be written into <em class="parameter"><code>infoLog</code></em>
is given by <em class="parameter"><code>bufSize</code></em>, and the actual number of characters written
into <em class="parameter"><code>infoLog</code></em> is returned in the integer whose address is given
by <em class="parameter"><code>length</code></em>. If <em class="parameter"><code>length</code></em> is <code class="constant">NULL</code>,
no length is returned.
</p><p>
The actual length of the info log for the program pipeline may be determined by calling
<a class="citerefentry" href="glGetProgramPipeline.xml"><span class="citerefentry"><span class="refentrytitle">glGetProgramPipeline</span></span></a> with
<em class="parameter"><code>pname</code></em> set to <code class="constant">GL_INFO_LOG_LENGTH</code>.

<code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>pipeline</code></em> is not
a name previously returned from a call to <a class="citerefentry" href="glGenProgramPipelines.xml"><span class="citerefentry"><span class="refentrytitle">glGenProgramPipelines</span></span></a>
or if such a name has been deleted by a call to
