The \c fb_format specifies which color components are in - * each pixel and what the default order is. For example, \c GL_RGB specifies - * that red, green, blue are available and red is in the "most significant" - * position and blue is in the "least significant".

The resulting mask values in the - * \c struct gl_config structure is \b identical to the \c GL_RGBA or - * \c GL_BGRA case, except the \c alphaMask is zero. This means that, as - * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8 - * still uses 32-bits. - * - * If in doubt, look at the tables used in the function. - * - * \param ptr_to_modes Pointer to a pointer to a linked list of - * \c struct gl_config. Upon completion, a pointer to - * the next element to be process will be stored here. - * If the function fails and returns \c GL_FALSE, this - * value will be unmodified, but some elements in the - * linked list may be modified. - * \param fb_format Format of the framebuffer. Currently only \c GL_RGB, - * \c GL_RGBA, \c GL_BGR, and \c GL_BGRA are supported. - * \param fb_type Type of the pixels in the framebuffer. Currently only - * \c GL_UNSIGNED_SHORT_5_6_5, - * \c GL_UNSIGNED_SHORT_5_6_5_REV, - * \c GL_UNSIGNED_INT_8_8_8_8, and - * \c GL_UNSIGNED_INT_8_8_8_8_REV are supported. - * \param depth_bits Array of depth buffer sizes to be exposed. - * \param stencil_bits Array of stencil buffer sizes to be exposed. - * \param num_depth_stencil_bits Number of entries in both \c depth_bits and - * \c stencil_bits. - * \param db_modes Array of buffer swap modes. If an element has a - * value of \c GLX_NONE, then it represents a - * single-buffered mode. Other valid values are - * \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and - * \c GLX_SWAP_UNDEFINED_OML. See the - * GLX_OML_swap_method extension spec for more details. - * \param num_db_modes Number of entries in \c db_modes. - * \param msaa_samples Array of msaa sample count. 0 represents a visual - * without a multisample buffer. - * \param num_msaa_modes Number of entries in \c msaa_samples. - * \param visType GLX visual type.

The \c fb_format specifies which color components are in + * each pixel and what the default order is. For example, \c GL_RGB specifies + * that red, green, blue are available and red is in the "most significant" + * position and blue is in the "least significant".

Upon completion, a pointer to + * the next element to be process will be stored here. + * If the function fails and returns \c GL_FALSE, this + * value will be unmodified, but some elements in the + * linked list may be modified. + * \param fb_format Format of the framebuffer. Currently only \c GL_RGB, + * \c GL_RGBA, \c GL_BGR, and \c GL_BGRA are supported. + * \param fb_type Type of the pixels in the framebuffer. Currently only + * \c GL_UNSIGNED_SHORT_5_6_5, + * \c GL_UNSIGNED_SHORT_5_6_5_REV, + * \c GL_UNSIGNED_INT_8_8_8_8, and + * \c GL_UNSIGNED_INT_8_8_8_8_REV are supported. + * \param depth_bits Array of depth buffer sizes to be exposed. + * \param stencil_bits Array of stencil buffer sizes to be exposed. + * \param num_depth_stencil_bits Number of entries in both \c depth_bits and + * \c stencil_bits. + * \param db_modes Array of buffer swap modes. If an element has a + * value of \c GLX_NONE, then it represents a + * single-buffered mode. Other valid values are + * \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and + * \c GLX_SWAP_UNDEFINED_OML.
