NAME
XQueryTree - query window tree information
SYNTAX
Status XQueryTree(Display *display, Window w, Window
*root_return, Window *parent_return, Window
**children_return, unsigned int *nchildren_return);
ARGUMENTS
children_return
Returns the list of children.
display
Specifies the connection to the X 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 window ID,
a pointer to the list of children windows
(NULL when there are no children),
and the number of children in the list for the specified window.
The children are listed in current stacking order, from bottom-most
(first) to top-most (last).
XQueryTree
returns zero if it fails and nonzero if it succeeds.
To free a non-NULL children list when it is no longer needed, use
XFree.
BUGS
This really should return a screen *, not a root window ID.
