Description

VI_ATTR_RD_BUF_OPER_MODE specifies the operational mode of the formatted I/O read buffer. When the operational mode is set to VI_FLUSH_DISABLE (default), the buffer is flushed only on explicit calls to viFlush(). If the operational mode is set to VI_FLUSH_ON_ACCESS, the read buffer is flushed every time a viScanf() (or related) operation completes.
