        <para>
            <function>glGetProgramPipelineInfoLog</function> retrieves the info log for the program
            pipeline object <parameter>pipeline</parameter>. The info log, including its null terminator,
            is written into the array of characters whose address is given by <parameter>infoLog</parameter>.
            The maximum number of characters that may be written into <parameter>infoLog</parameter>
            is given by <parameter>bufSize</parameter>, and the actual number of characters written
            into <parameter>infoLog</parameter> is returned in the integer whose address is given
            by <parameter>length</parameter>. If <parameter>length</parameter> is <constant>NULL</constant>,
            no length is returned.

        <para>
            The actual length of the info log for the program pipeline may be determined by calling
