Prompts the user to select an item or items from a choice.
The function 
prompt-with-message
 displays 
message
 in a dialog owned by 
owner
.
prompts the user with a choice. The user's selection is normally returned by the prompter.
If 
continuation
 is non-
nil
, then it must be a function with a lambda list that accepts two arguments. The 
continuation
 function is called with the values that would normally be returned by 
prompt-with-message
. On Cocoa, passing 
continuation
 causes the dialog to be made as a window-modal sheet and 
prompt-with-message
 returns immediately, leaving the dialog on the screen. The with-dialog-results macro provides a convenient way to create a 
continuation
 function.
