io.flush()
This function saves buffered data to a file.
Type TSP-Link accessible Affected by Where saved Default value
Function Yes
Usage
io.flush()
Details
You must use the
io.flush()
or
io.close()
functions to write data to the file system.
Data is not automatically written to a file when you use the
io.write()
function. The
io.write()
function buffers data; it may not be written to the USB flash drive immediately. Use the
io.flush()
function to immediately write buffered data to the drive.
This function only flushes the default output file.
