Browse source

1.0.  This commit updates it to correspond to the way IDs are chosen in
versions >= 1.0.

<title>Creating Objects</title>
<para>
Each object has a unique ID. The IDs are allocated by the
client, from a range of IDs. The server tracks how many
IDs are left in the current range and sends a new range
when the client is about to run out.
Each object has a unique ID. The IDs are allocated by the entity
creating the object (either client or server). IDs allocated by the
client are in the range [1, 0xfeffffff] while IDs allocated by the
server are in the range [0xff000000, 0xffffffff]. The 0 ID is
reserved to represent a null or non-existant object.
For efficiency purposes, the IDs are densely packed in the sense that
the ID N will not be used until N-1 has been used. Any ID allocation
algorithm that does not maintain this property is incompatible with
the implementation in libwayland.
