SeaMaxLinRead() int SeaMaxLinRead ( SeaMaxLin *  SeaMaxPointer, slave_address_t  slaveId, seaio_type_t  type, address_loc_t  starting_address, address_range_t  range, void *  data  ) Read from a module. This is a multifunction read that can read from a module previously opened. Any SeaIO devices attached to that module can then be read from in one of the following ways. Parameters [in] *SeaMaxPointer Pointer to an open seaMaxModule. [in] slaveId Address of the device you wish to read. [in] type The read type to preform. [in] starting_address Where to start the read; MODBUS is base 1. [in] range How many consecutive addresses to read. [out] *data Pointer to data storage buffer. Returns int Error code. Return values >0 Number of bytes of data in the buffer. -EBADF No module open or write error. -EINVAL Null buffer or too much data in buffer. -ENOMEM Low memory. -ENODEV Didn't receive response. -EFAULT MODBUS exception. First byte of buffer contains exception. References NO_CONNECT. Referenced by CSeaMaxLin::Read().
