Description
VI_ATTR_WR_BUF_OPER_MODE specifies the operational mode of the formatted I/O write buffer. When the operational mode is set to VI_FLUSH_WHEN_FULL (default), the buffer is flushed when an END indicator is written to the buffer, or when the buffer fills up. If the operational mode is set to VI_FLUSH_ON_ACCESS, the write buffer is flushed under the same conditions, and also every time a viPrintf() (or related) operation completes.
