XFree(3) XLIB FUNCTIONS XFree(3)NAME
XFree - free client data
int XFree(void *data);
data Specifies the data that are to be freed.
The XFree function is a general-purpose Xlib routine that frees the specified data. You must use it to free any objects that were allo-
cated by Xlib, unless an alternate function is explicitly specified for the object. A NULL pointer cannot be passed to this function.

XQueryTree(3) XLIB FUNCTIONS XQueryTree(3)NAME
XQueryTree - query window tree information
Status XQueryTree(Display *display, Window w, Window *root_return, Window *parent_return, Window **children_return, unsigned int *nchil-
Returns the list of children.
display Specifies the connection to the X server.
Returns the number of children.
Returns the parent window.
Returns the root window.
w Specifies the window whose list of children, root, parent, and number of children you want to obtain.
The XQueryTree function returns the root ID, the parent window ID, a pointer to the list of children windows (NULL when there are no chil-
dren), 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.
XQueryTree can generate a BadWindow error.
This really should return a screen *, not a root window ID.
BadWindow A value for a Window argument does not name a defined Window.
