dp_atexit option ?cmd?
The dp_atexit command manages the dp_atexit list, a list of
callback routines that are evaluated just before the tcl+tk application
is exited. This is useful for applications where clean up actions must be
performed before a process can safely exit.
The argument option specifies the operation to be performed
on the dp_atexit list. The valid options are:
dp_atexit list
Returns the current dp_atexit list.
dp_atexit set newList
Sets the dp_atexit list newList.
dp_atexit append callback
Append callback to the end of the dp_atexit list.
dp_atexit appendUnique callback
Appends callback to the end of the dp_atexit list if
it's not already a member of the list.
dp_atexit prepend callback
Inserts callback at the front of the dp_atexit list.
dp_atexit insert beforeCallback callback
Inserts callback before beforeCallback in the dp_atexit
list. If beforeCallback is not in
the dp_atexit list, no action is taken.
dp_atexit delete callback
Delete callback from the dp_atexit list.
If callback is not in the dp_atexit list, no action is taken.
dp_atexit clear
Clears the dp_atexit list.
