fileVar:flush()
This function writes buffered data to a file.
Type TSP-Link accessible
Affected by Where saved Default value
Function No
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 fileVar:flush() to flush this data. Using this function removes the need to close a file
after writing to it, allowing the file 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.
