TestForExistingItem()

static bool TestForExistingItem ( BOARD *  aPcb, BOARD_ITEM *  aItem  )

static

Function TestForExistingItem Test if aItem exists somewhere in undo/redo lists of items.

Used by PutDataInPreviousState to be sure an item was not deleted since an undo or redo. This could be possible:

• if a call to SaveCopyInUndoList was forgotten in Pcbnew
• in zones outlines, when a change in one zone merges this zone with an other Before using this function to test existence of items, it must be called with aItem = NULL to prepare the list

  Parameters

  aPcb	= board to test
  aItem	= item to find = NULL to build the list of existing items
