JET_SNPROG Structure

The JET_SNPROG structure contains information about the progress of a long-running operation. When the callback function is called to notify the status of the operation and the operation is still in progress, the last parameter of the callback function is a pointer to a JET_SNPROG structure.

    typedef struct {
      unsigned long cbStruct;
      unsigned long cunitDone;
      unsigned long cunitTotal;
    } JET_SNPROG;
