2003-2014 The Khronos Group Inc. eglGetConfigAttrib 3G eglGetConfigAttrib return information about an EGL frame buffer configuration EGLBoolean eglGetConfigAttrib EGLDisplay display EGLConfig config EGLint attribute EGLint * value display Specifies the EGL display connection. config Specifies the EGL frame buffer configuration to be queried. attribute Specifies the EGL rendering context attribute to be returned. value Returns the requested value. eglGetConfigAttrib returns in value the value of attribute for config (config attributes are described in more detail in the eglChooseConfig reference page). attribute can be one of the following: EGL_ALPHA_SIZE Returns the number of bits of alpha stored in the color buffer. EGL_ALPHA_MASK_SIZE Returns the number of bits in the alpha mask buffer. EGL_BIND_TO_TEXTURE_RGB Returns EGL_TRUE if color buffers can be bound to an RGB texture, EGL_FALSE otherwise. EGL_BIND_TO_TEXTURE_RGBA Returns EGL_TRUE if color buffers can be bound to an RGBA texture, EGL_FALSE otherwise. EGL_BLUE_SIZE Returns the number of bits of blue stored in the color buffer. EGL_BUFFER_SIZE Returns the depth of the color buffer. It is the sum of EGL_RED_SIZE, EGL_GREEN_SIZE, EGL_BLUE_SIZE, and EGL_ALPHA_SIZE. EGL_COLOR_BUFFER_TYPE Returns the color buffer type. Possible types are EGL_RGB_BUFFER and EGL_LUMINANCE_BUFFER. EGL_CONFIG_CAVEAT Returns the caveats for the frame buffer configuration. Possible caveat values are EGL_NONE, EGL_SLOW_CONFIG, and EGL_NON_CONFORMANT. EGL_CONFIG_ID Returns the ID of the frame buffer configuration. EGL_CONFORMANT Returns a bitmask indicating which client API contexts created with respect to this config are conformant. EGL_DEPTH_SIZE Returns the number of bits in the depth buffer. EGL_GREEN_SIZE Returns the number of bits of green stored in the color buffer. EGL_LEVEL Returns the frame buffer level. Level zero is the default frame buffer. Positive levels correspond to frame buffers that overlay the default buffer and negative levels correspond to frame buffers that underlay the default buffer. EGL_LUMINANCE_SIZE Returns the number of bits of luminance stored in the luminance buffer. EGL_MAX_PBUFFER_WIDTH Returns the maximum width of a pixel buffer surface in pixels. EGL_MAX_PBUFFER_HEIGHT Returns the maximum height of a pixel buffer surface in pixels. EGL_MAX_PBUFFER_PIXELS Returns the maximum size of a pixel buffer surface in pixels. EGL_MAX_SWAP_INTERVAL Returns the maximum value that can be passed to eglSwapInterval. EGL_MIN_SWAP_INTERVAL Returns the minimum value that can be passed to eglSwapInterval. EGL_NATIVE_RENDERABLE Returns EGL_TRUE if native rendering APIs can render into the surface, EGL_FALSE otherwise. EGL_NATIVE_VISUAL_ID Returns the ID of the associated native visual. EGL_NATIVE_VISUAL_TYPE Returns the type of the associated native visual. EGL_RED_SIZE Returns the number of bits of red stored in the color buffer. EGL_RENDERABLE_TYPE Returns a bitmask indicating the types of supported client API contexts. EGL_SAMPLE_BUFFERS Returns the number of multisample buffers. EGL_SAMPLES Returns the number of samples per pixel. EGL_STENCIL_SIZE Returns the number of bits in the stencil buffer. EGL_SURFACE_TYPE Returns a bitmask indicating the types of supported EGL surfaces. EGL_TRANSPARENT_TYPE Returns the type of supported transparency. Possible transparency values are: EGL_NONE, and EGL_TRANSPARENT_RGB. EGL_TRANSPARENT_RED_VALUE Returns the transparent red value. EGL_TRANSPARENT_GREEN_VALUE Returns the transparent green value. EGL_TRANSPARENT_BLUE_VALUE Returns the transparent blue value. EGL_CONFORMANT is supported only if the EGL version is 1.3 or greater. EGL_ALPHA_MASK_SIZE, EGL_COLOR_BUFFER_TYPE, EGL_LUMINANCE_SIZE, and EGL_RENDERABLE_TYPE are supported only if the EGL version is 1.2 or greater. While EGL_MATCH_NATIVE_PIXMAP can be specified in the attribute list passed to eglChooseConfig, it is not an attribute of the resulting config and cannot be queried using eglGetConfigAttrib. EGL_FALSE is returned on failure, EGL_TRUE otherwise. value is not modified when EGL_FALSE is returned. EGL_BAD_DISPLAY is generated if display is not an EGL display connection. EGL_NOT_INITIALIZED is generated if display has not been initialized. EGL_BAD_CONFIG is generated if config is not an EGL frame buffer configuration. EGL_BAD_ATTRIBUTE is generated if attribute is not a valid frame buffer configuration attribute. eglChooseConfig, eglGetConfigs
