31    EGL device extension

33Dependencies
34
35    This extension is written against the language of EGL 1.5 as
36    modified by EGL_EXT_device_query.
37
38    EGL_EXT_device_query is required.

40Overview
41
42    ANGLE has the ability to run GPU commands on a native D3D device.
43    This extension defines a mapping from an EGL device to a D3D
44    device, after it's queried from an EGL display.

60    Accepted as a queried <attribute> in eglQueryDeviceAttribEXT:
61
62        EGL_D3D9_DEVICE_ANGLE              0x33A0
63        EGL_D3D11_DEVICE_ANGLE             0x33A1
64
65Add a new section 2.1.3 (D3D Devices) after 2.1.2 (Devices)
66
67    Somewhat analogous to an EGL device, a D3D device establishes a
68    namespace for D3D operations. In the D3D APIs, such devices are
69    represented by pointers. For more details, see the D3D
70    documentation.
71
72Changes to section 3.2 (Devices)
73
74    Replace the paragraph immediately following the prototype for
75    eglQueryDeviceAttribEXT:
76
77    <attribute> may be either EGL_D3D9_DEVICE_ANGLE or EGL_D3D11_DEVICE_ANGLE.
78    On success, EGL_TRUE is returned, and a valid D3D9 or D3D11 device pointer
79    corresponding to the EGL device is returned in <value>. This handle
80    is compatible with D3D API functions. If the EGL device is not currently
81    associated with a D3D9 device and <attribute> is EGL_D3D9_DEVICE_ANGLE,
82    or if the EGL device is not currently associated with a D3D11 device and
83    <attribute> is EGL_D3D11_DEVICE_ANGLE, EGL_BAD_ATTRIBUTE is returned,
84    and <value> is left unchanged.
