XQueryTree __libmansuffix__ __xorgversion__ "XLIB FUNCTIONS"
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 1i
Returns the list of children.
display 1i
Specifies the connection to the X server.
nchildren_return 1i
Returns the number of children.
parent_return 1i
Returns the parent window.
root_return 1i
Returns the root window.
w 1i
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 . XQueryTree can generate a BadWindow error.
BUGS
This really should return a screen *, not a root window ID.
DIAGNOSTICS
1i BadWindow A value for a Window argument does not name a defined Window.
