+ EGL Extension #??
+
+Dependencies
+
+ This extension is written against the wording of the EGL 1.4
+ Specification.
+
+Overview
+
+ This extension allows querying pointer-sized surface attributes,
+ thus avoiding problems with coercing 64-bit pointers into a 32-bit
+ integer.
+
+New Types
+
+ None
+
+New Procedures and Functions
+
+ EGLBoolean eglQuerySurfacePointerANGLE(
+ EGLDisplay dpy,
+ EGLSurface surface,
+ EGLint attribute,
+ void **value);
+
+New Tokens
+
+ None
+
+Additions to Chapter 3 of the EGL 1.4 Specification (EGL Functions and Errors)
+
+ Add to the end of the paragraph starting with "To query an
+ attribute associated with an EGLSurface" in section 3.5.6,
+ "Surface Attributes":
+
+ "If the attribute type in table 3.5 is 'pointer', then
+ eglQuerySurface returns EGL_FALSE and an EGL_BAD_PARAMETER error
+ is generated. To query pointer attributes, call:
+
+ EGLBoolean eglQuerySurfacePointerANGLE(
+ EGLDisplay dpy,
+ EGLSurface surface,
+ EGLint attribute,
+ void **value);
+
+ eglQuerySurfacePointerANGLE behaves identically to eglQuerySurface,
+ except that only attributes of type 'pointer' can be queried.
+ If an attribute queried via eglQuerySurfacePointerANGLE is not
+ of type 'pointer', then eglQuerySurfacePointer returns EGL_FALSE
+ and an EGL_BAD_PARAMETER error is generated."
