NAME
XQueryTree - query window tree information
SYNTAX
Status XQueryTree(display, w, root_return, parent_return,
children_return, nchildren_return)
Display *display;
Window w;
Window *root_return;
Window *parent_return;
Window **children_return;
unsigned int *nchildren_return;
ARGUMENTS
children_return
Returns a pointer to the list of children.
display Specifies the connection to the XWIN server.
nchildren_return
Returns the number of children.
parent_return
Returns the parent window.
root_return
Returns the root window.
w Specifies the window whose list of children, root,
parent, and number of children you want to obtain.
DESCRIPTION
The XQueryTree function returns the root ID, the parent win-
dow 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 bot-
tommost (first) to topmost (last). XQueryTree returns zero
if it fails and nonzero if it succeeds. To free this list
when it is no longer needed, use XFree.
BUGS
This really should return a screen *, not a root window ID.
