2051 the minibuffer does not count, only windows from WINDOW's frame count
|

2052

2053 If optional third arg ALL-FRAMES t means include windows on all frames.
|
|
|
2054 ALL-FRAMES nil or omitted means cycle within the frames as specified
|
|
|
2055 above. ALL-FRAMES = `visible' means include windows on all visible frames.
|
|
|
2056 ALL-FRAMES = 0 means include windows on all visible and iconified frames.
|
|
|
2057 If ALL-FRAMES is a frame, restrict search to windows on that frame.
|
|

2058 Anything else means restrict to WINDOW's frame.
|
|
|
2059
|
|

2060 Optional fourth argument CONSOLE controls which consoles or devices the
|
|
|
2061 returned window may be on. If CONSOLE is a console, return windows only
|
|
|
2062 on that console. If CONSOLE is a device, return windows only on that
|
|
|
2063 device. If CONSOLE is a console type, return windows only on consoles
|
|
|
2064 of that type. If CONSOLE is 'window-system, return any windows on any
|
|
|
2065 window-system consoles. If CONSOLE is nil or omitted, return windows only
|
|
|
2066 on WINDOW's console. Otherwise, all windows are considered.

|
|
2067
|
|
|
2068 If you use consistent values for MINIBUF, ALL-FRAMES, and CONSOLE, you
|
|
|
2069 can use `previous-window' to iterate through the entire cycle of acceptable
|
|
|
2070 windows, eventually ending up back at the window you started with.
|
|
|
2071 `next-window' traverses the same cycle, in the reverse order.

4495 The values returned are in the form an alist of usage types and byte

4496 counts. The byte counts attempt to encompass all the memory used

4497 by the window (separate from the memory logically associated with a

4498 buffer or frame), including internal structures and any malloc()

4499 overhead associated with them. In practice, the byte counts are

4500 underestimated because certain memory usage is very hard to determine
|
|
|
4501 (e.g. the amount of memory used inside the Xt library or inside the
|
|
|
4502 X server) and because there is other stuff that might logically
|
|
|
4503 be associated with a window, buffer, or frame (e.g. window configurations,
|
|
|
4504 glyphs) but should not obviously be included in the usage counts.

4505
|
|

4506 Multiple slices of the total memory usage may be returned, separated
|
|

4507 by a nil. Each slice represents a particular view of the memory, a
|
|
|
4508 particular way of partitioning it into groups. Within a slice, there
|
|
|
4509 is no overlap between the groups of memory, and each slice collectively
|
|

4510 represents all the memory concerned.
