|
|
* @Title: Properties and Atoms
|
|
*
|
|
* Each window under X can have any number of associated
|
|
* “properties” attached to it.
|
|
* Properties are arbitrary chunks of data identified by
|
|
* “atom”s. (An “atom”
|
|
* is a numeric index into a string table on the X server. They are used
|
|
* to transfer strings efficiently between clients without
|
|
* having to transfer the entire string.) A property
|
|
* has an associated type, which is also identified
|
|
* using an atom.
|
|
*
|
|
* A property has an associated “format”,
|
|
* an integer describing how many bits are in each unit
|
|
* of data inside the property. It must be 8, 16, or 32.
|
|
* When data is transferred between the server and client,
|
|
* if they are of different endianesses it will be byteswapped
|
|
* as necessary according to the format of the property.
|
|
* Note that on the client side, properties of format 32
|
|
* will be stored with one unit per long,
|
|
* even if a long integer has more than 32 bits on the platform.
|
|
* (This decision was apparently made for Xlib to maintain
|
|
* compatibility with programs that assumed longs were 32
|
|
* bits, at the expense of programs that knew better.)
|
|
*
|
|
* The functions in this section are used to add, remove
|
|
* and change properties on windows, to convert atoms
|
|
* to and from strings and to manipulate some types of
|
|
* data commonly stored in X window properties.
