变量结构体

typedef struct {
  VARIABLE_HEADER *CurrPtr;
  //
  // If both ADDED and IN_DELETED_TRANSITION variable are present,
  // InDeletedTransitionPtr will point to the IN_DELETED_TRANSITION one.
  // Otherwise, CurrPtr will point to the ADDED or IN_DELETED_TRANSITION one,
  // and InDeletedTransitionPtr will be NULL at the same time.
  //
  VARIABLE_HEADER *InDeletedTransitionPtr;
  VARIABLE_HEADER *EndPtr;
  VARIABLE_HEADER *StartPtr;
  BOOLEAN         Volatile;
} VARIABLE_POINTER_TRACK;

如果同时存在

• ADDED
• IN_DELETED_TRANSITION

变量, InDeletedTransitionPtr将指向IN_DELETED_TRANSITION

否则，CurrPtr将指向ADDED或IN_DELETED_TRANSITION 1，并且InDeletedTransitionPtr将同时为NULL。
