elisp: Frame Configuration Type

 
 2.4.7 Frame Configuration Type
 ------------------------------
 
 A “frame configuration” stores information about the positions, sizes,
 and contents of the windows in all frames.  It is not a primitive
 type—it is actually a list whose CAR is ‘frame-configuration’ and whose
 CDR is an alist.  Each alist element describes one frame, which appears
 as the CAR of that element.
 
    SeeFrame Configurations, for a description of several functions
 related to frame configurations.
