Getting the process ID (MenuKillCB)

The first callback, MenuKillCB, is invoked each time a user selects Kill Selected from the Process menu, or double-clicks on an item in the process list.

This callback must:

Obtain the process ID (PID) of the process that the user selected.
Display the question dialog.

All callbacks are passed a parameter named cbs. The cbs parameter is a callback structure and contains various useful information. At the least, cbs contains the handle of the calling widget and the handle of the dialog in which the calling widget was located. It may also contain other information, depending on the type of widget that called it. For example, if it was called from a text widget, cbs would also contain the widget's associated text string.
