_________________________________________________________________

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.
