eglGetDisplay — return an EGL display connection
EGLDisplay eglGetDisplay(
|
NativeDisplayType native_display) ; |
native_display
Specifies the display to connect to.
EGL_DEFAULT_DISPLAY
indicates the default display.
eglGetDisplay
obtains the
EGL display connection for the native
display native_display
.
The behavior of eglGetDisplay
is similar to
that of
eglGetPlatformDisplay,
but is specified in terms of implementation-specific behavior
rather than platform-specific extensions. As for
eglGetPlatformDisplay,
EGL considers the returned EGLDisplay as belonging
to the same platform as display_id
.
However, the set of platforms to which
display_id
is permitted to belong, as
well as the actual type of display_id
,
are implementation-specific. If
display_id
is
EGL_DEFAULT_DISPLAY
, a default
display is returned. Multiple calls made to
eglGetDisplay
with the same
display_id
will return the same
EGLDisplay handle.
If display_id
is
EGL_DEFAULT_DISPLAY
, a default display connection is returned.
If no display connection matching native_display
is
available, EGL_NO_DISPLAY
is returned. No
error is generated.
Use eglInitialize to initialize the display connection.
