eglCopyBuffers — copy EGL surface color buffer to a native pixmap
EGLBoolean eglCopyBuffers(
|
EGLDisplay display, |
EGLSurface surface, | |
NativePixmapType native_pixmap) ; |
display
Specifies the EGL display connection.
surface
Specifies the EGL surface whose color buffer is to be copied.
native_pixmap
Specifies the native pixmap as target of the copy.
eglCopyBuffers
copies the color buffer of
surface
to native_pixmap
.
eglCopyBuffers
performs an implicit
glFlush
before it returns. Subsequent
GL commands may be issued immediately after calling
eglCopyBuffers
,
but are not executed until copying of the color buffer is completed.
The color buffer of surface
is left unchanged
after calling eglCopyBuffers
.
EGL_FALSE
is returned if swapping of the
surface buffers fails, EGL_TRUE
otherwise.
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_SURFACE
is generated if
surface
is not an EGL drawing surface.
EGL_BAD_NATIVE_PIXMAP
is generated if
the implementation does not support native pixmaps.
EGL_BAD_NATIVE_PIXMAP
may be generated if
native_pixmap
is not a valid native pixmap.
EGL_BAD_MATCH
is generated if
the format of native_pixmap
is not compatible
with the color buffer of surface
.
EGL_CONTEXT_LOST
is generated if a power management
event has occurred. The application must destroy all contexts and
reinitialise OpenGL ES state and objects to continue rendering.
