  • lpInBuffer
    [in] Pointer to an array of BLOCK_RUN structures. Each element of the array specifies a single run of blocks to lock. All other blocks should be unlocked.
  • nInBufferSize
    [in] Size of the BLOCK_RUN structure multiplied by the number of elements in the array.
  • lpOutBuffer
    Not used. Set to NULL.
  • nOutBufferSize
    Not used. Set to zero (0).
  • lpBytesReturned
    Not used. Set to NULL.
