| michael@0 | 29 | EGL Extension #28 |
| michael@0 | 30 | |
| michael@0 | 31 | Dependencies |
| michael@0 | 32 | |
| michael@0 | 33 | This extension is written against the wording of the EGL 1.4 |
| michael@0 | 34 | Specification. |
| michael@0 | 35 | |
| michael@0 | 36 | Overview |
| michael@0 | 37 | |
| michael@0 | 38 | This extension allows querying pointer-sized surface attributes, |
| michael@0 | 39 | thus avoiding problems with coercing 64-bit pointers into a 32-bit |
| michael@0 | 40 | integer. |
| michael@0 | 41 | |
| michael@0 | 42 | New Types |
| michael@0 | 43 | |
| michael@0 | 44 | None |
| michael@0 | 45 | |
| michael@0 | 46 | New Procedures and Functions |
| michael@0 | 47 | |
| michael@0 | 48 | EGLBoolean eglQuerySurfacePointerANGLE( |
| michael@0 | 49 | EGLDisplay dpy, |
| michael@0 | 50 | EGLSurface surface, |
| michael@0 | 51 | EGLint attribute, |
| michael@0 | 52 | void **value); |
| michael@0 | 53 | |
| michael@0 | 54 | New Tokens |
| michael@0 | 55 | |
| michael@0 | 56 | None |
| michael@0 | 57 | |
| michael@0 | 58 | Additions to Chapter 3 of the EGL 1.4 Specification (EGL Functions and Errors) |
| michael@0 | 59 | |
| michael@0 | 60 | Add to the end of the paragraph starting with "To query an |
| michael@0 | 61 | attribute associated with an EGLSurface" in section 3.5.6, |
| michael@0 | 62 | "Surface Attributes": |
| michael@0 | 63 | |
| michael@0 | 64 | "If the attribute type in table 3.5 is 'pointer', then |
| michael@0 | 65 | eglQuerySurface returns EGL_FALSE and an EGL_BAD_PARAMETER error |
| michael@0 | 66 | is generated. To query pointer attributes, call: |
| michael@0 | 67 | |
| michael@0 | 68 | EGLBoolean eglQuerySurfacePointerANGLE( |
| michael@0 | 69 | EGLDisplay dpy, |
| michael@0 | 70 | EGLSurface surface, |
| michael@0 | 71 | EGLint attribute, |
| michael@0 | 72 | void **value); |
| michael@0 | 73 | |
| michael@0 | 74 | eglQuerySurfacePointerANGLE behaves identically to eglQuerySurface, |
| michael@0 | 75 | except that only attributes of type 'pointer' can be queried. |
| michael@0 | 76 | If an attribute queried via eglQuerySurfacePointerANGLE is not |
| michael@0 | 77 | of type 'pointer', then eglQuerySurfacePointer returns EGL_FALSE |
| michael@0 | 78 | and an EGL_BAD_PARAMETER error is generated." |
