#
# Example:

# source code:
# struct bar {

# int integer;
# void *ptr;
# };
# const int *iPtr;
# };
#
# class foo {
# public:
# int a;
# struct {
# int b;
# struct bar *c;
# };
# };
#
# foo *f = new foo (); <-- break here
#
# We want to check all the children of "f".
#
# Translate the above structures into the following tree:
#
# set tree {
# foo f {
# {} public {
# int a {}
# anonymous struct {
# {} public {
# int b {}
# {bar *} c {
# {} public {
# anonymous union {
# {} public {
# int integer {}
# {void *} ptr {}
# }
# }
# {const int *} iPtr {
# {const int} {*iPtr} {}

#
# If you'd prefer to walk the tree using your own callback,
# simply pass the name of the callback to mi_walk_varobj_tree.
#
# This callback should take one argument, the name of the variable
# to process. This name is the name of a global array holding the
# variable's properties (object name, type, etc).
#
# An example callback:
#
# proc my_callback {var} {
# upvar #0 $var varobj
#

#
# The arrays created for each variable object contain the following
# members:
#
# obj_name - the object name for accessing this variable via MI
# display_name - the display name for this variable (exp="display_name" in
# the output of -var-list-children)
# type - the type of this variable (type="type" in the output
# of -var-list-children, or the special tag "anonymous"
# path_expr - the "-var-info-path-expression" for this variable
# NOTE: This member cannot be used reliably with typedefs.
# Use with caution!
# See notes inside get_path_expr for more.
# parent - the variable name of the parent varobj
# children - a list of children variable names (which are the
# names Tcl arrays, not object names)
#
# For each variable object, an array containing the above fields will
# be created under the root node (conveniently called, "root"). For example,
# a variable object with handle "OBJ.public.0_anonymous.a" will have
# a corresponding global Tcl variable named "root.OBJ.public.0_anonymous.a".
