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.

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."
