            <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
