|
|
The
|
|
.ZN XQueryTree
|
|
function returns the root ID, the parent window ID,
|
|
a pointer to the list of children windows,
|
|
and the number of children in the list for the specified window.
|
|
The children are listed in current stacking order, from bottommost
|
|
(first) to topmost (last).
|
|
.ZN XQueryTree
|
|
returns zero if it fails and nonzero if it succeeds.
|
|
To free this list when it is no longer needed, use
|
|
.ZN XFree .
|
|
.SH BUGS
|
|
This really should return a screen *, not a root window ID.
|
|
