gf_3d_query_config()

Query a 3D configuration

Synopsis:

#include <gf3d.h>

int gf_3d_query_config( gf_3d_config_info_t*    info,
                        gf_dev_t                dev,
                        EGLDisplay              display,
                        EGLConfig               cfg  );

Arguments:

info

A pointer to a gf_3d_config_info_t structure that the function fills with information about the attributes required to create a GF surface for a 3D configuration. See below.

dev

The handle for the graphics device to query. This is the handle acquired by gf_dev_attach().

display

The EGL display you want to query.

cfg

The EGLConfig ID you want to query. You can select the EGLConfig ID from a list returned by eglChooseConfig().

Library:

gf

Description:

This function lets you translate EGL configuration attributes into GF attributes. This lets you create a GF surface that can render 3D content. For a given EGL configuration, you can find out:

• The gf_format_t of the color buffer: info->format.
• The flags you should OR into the flags argument of gf_surface_create_*() to make sure the allocated surface is 3D renderable: info->create_flags.

Returns:

GF_ERR_OK

Success.

Classification:

QNX Graphics Framework
