| 29 EGL Extension #28 | |
| 30 | |
| 31 Dependencies | |
| 32 | |
| 33 This extension is written against the wording of the EGL 1.4 | |
| 34 Specification. | |
| 35 | |
| 36 Overview | |
| 37 | |
| 38 This extension allows querying pointer-sized surface attributes, | |
| 39 thus avoiding problems with coercing 64-bit pointers into a 32-bit | |
| 40 integer. | |

| 42 New Types | |

| 45 | |
| 46 New Procedures and Functions | |
| 47 | |
| 48 EGLBoolean eglQuerySurfacePointerANGLE( | |
| 49 EGLDisplay dpy, | |
| 50 EGLSurface surface, | |
| 51 EGLint attribute, | |
| 52 void **value); | |

| 58 Additions to Chapter 3 of the EGL 1.4 Specification (EGL Functions and Errors) | |
| 59 | |
| 60 Add to the end of the paragraph starting with "To query an | |
| 61 attribute associated with an EGLSurface" in section 3.5.6, | |
| 62 "Surface Attributes": | |
| 63 | |
| 64 "If the attribute type in table 3.5 is 'pointer', then | |
| 65 eglQuerySurface returns EGL_FALSE and an EGL_BAD_PARAMETER error | |
| 66 is generated. To query pointer attributes, call: | |
| 67 | |
| 68 EGLBoolean eglQuerySurfacePointerANGLE( | |
| 69 EGLDisplay dpy, | |
| 70 EGLSurface surface, | |
| 71 EGLint attribute, | |
| 72 void **value); | |
| 73 | |
| 74 eglQuerySurfacePointerANGLE behaves identically to eglQuerySurface, | |
| 75 except that only attributes of type 'pointer' can be queried. | |
| 76 If an attribute queried via eglQuerySurfacePointerANGLE is not | |
| 77 of type 'pointer', then eglQuerySurfacePointer returns EGL_FALSE | |
| 78 and an EGL_BAD_PARAMETER error is generated." | |
