Upon completion, a pointer to 141 * the next element to be process will be stored here. 142 * If the function fails and returns \c GL_FALSE, this 143 * value will be unmodified, but some elements in the 144 * linked list may be modified. 145 * \param format Mesa mesa_format enum describing the pixel format 146 * \param depth_bits Array of depth buffer sizes to be exposed. 147 * \param stencil_bits Array of stencil buffer sizes to be exposed. 148 * \param num_depth_stencil_bits Number of entries in both \c depth_bits and 149 * \c stencil_bits. 150 * \param db_modes Array of buffer swap modes.
