The TMBlockIO API call is a general purpose block transfer function. A TMTouchReset is done followed by TMTouchByte(s) of all of the 'num_tran' bytes in the 'tran_buffer' data buffer. The values returned from the TMTouchByte(s) are placed back into the 'tran_buffer' data buffer. This call returns a byte length greater than or equal to 0 for success or one of the TRANSPORT error values described for a failure. The maximum number of 'num_tran' is 1023 bytes.
For a description of the above types, see the TMEX Type Descriptions.
Specifies the session handle returned from the API function TMExtendedStartSession that specifies the desired 1-Wire network port. This parameter is required by most TMEX API functions.
Specifies a pointer to a memory location that contains the data to write and then read from the 1-Wire network.
Specifies the number of bytes in the ‘tran_buffer ’ to transfer to and from the 1-Wire network.
>=0 => length of data sent and received from The 1-Wire network
<0 => TMEX Transport Error Return Code
