// Luckily, as of xorg 1.6.0 / X protocol 11 rev 0, the only pointer

// field contained in any of these specific X*Event structs is a
|
|
// |Display*|. So to simplify serializing these XEvents, we make the

|
// ********** XXX ASSUMPTION XXX **********
|
|
//
|
|
// that the process to which the event is forwarded shares the same
|
|
// display as the process on which the event originated.
|
|
//
|
|
// With this simplification, serialization becomes a simple memcpy to
|
|
// the output stream. Deserialization starts as just a memcpy from
|
|
// the input stream, BUT we then have to write the correct |Display*|
|
|
// into the right field of each X*Event that contains one.
