<pre>eglconfig.c:727
i think this should return false
<a href="http://www.khronos.org/registry/egl/sdk/docs/man/xhtml/eglChooseConfig.html">http://www.khronos.org/registry/egl/sdk/docs/man/xhtml/eglChooseConfig.html</a>
i was trying to run this function with
const EGLint pi32ConfigAttribs[] =
{
EGL_LEVEL, 0,
EGL_SURFACE_TYPE, EGL_WINDOW_BIT,
EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
EGL_NATIVE_RENDERABLE, EGL_FALSE,
EGL_DEPTH_SIZE, EGL_DONT_CARE,
EGL_NONE
};
and it would fail matching a config but the function would return true letting
me think that everything went fine.

href="show_bug.cgi?id=50870">https://bugs.freedesktop.org/show_bug.cgi?id=50870</a> <-- might be similar to this
i changed the data to this
EGLint pi32ConfigAttribs[5];
pi32ConfigAttribs[0] = EGL_SURFACE_TYPE;
pi32ConfigAttribs[1] = EGL_WINDOW_BIT;
pi32ConfigAttribs[2] = EGL_RENDERABLE_TYPE;
pi32ConfigAttribs[3] = EGL_OPENGL_ES2_BIT;
pi32ConfigAttribs[4] = EGL_NONE;
and it worked</pre>
