30 | | // XEvent is defined as a union of all more specific X*Events. |
31 | | // Luckily, as of xorg 1.6.0 / X protocol 11 rev 0, the only pointer |
32 | | // field contained in any of these specific X*Event structs is a |
33 | | // |Display*|. So to simplify serializing these XEvents, we make the |
34 | | // |
35 | | // ********** XXX ASSUMPTION XXX ********** |
36 | | // |
37 | | // that the process to which the event is forwarded shares the same |
38 | | // display as the process on which the event originated. |
39 | | // |
40 | | // With this simplification, serialization becomes a simple memcpy to |
41 | | // the output stream. Deserialization starts as just a memcpy from |
42 | | // the input stream, BUT we then have to write the correct |Display*| |
43 | | // into the right field of each X*Event that contains one. |
