Usage
fileVar
:flush()
fileVar
The file descriptor variable to flush
Details
The
fileVar
:write()
or
io.write()
functions buffer data, which may not be written immediately to the
USB flash drive. Use this function to flush this data. Using this function removes the need to close a file after
writing to it, allowing it to be left open to write more data. Data may be lost if the file is not closed or flushed
before a script ends.
If there is going to be a time delay before more data is written to a file, and you want to keep the file open, flush
the file after you write to it to prevent loss of data.
