file.flush()
This function writes buffering data to a file on the USB flash drive.
Type

Default value
Function
No
Usage
file.flush(
fileNumber
)
fileNumber
The file number returned from the
file.open()
function to flush
Details
The
file.write()
function may be buffering data instead of writing immediately to the USB flash
drive. Use
file.flush()
to flush this 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, flush the file to prevent loss of
data because of an aborted test.
Example
reset()
-- Fix the range to 10 V
smu.measure.range = 10
-- Set the measurement count to 100
smu.measure.count = 100
-- Set up reading buffers
-- Ensure the default measurement buffer size matches the count
defbuffer1.capacity = 100
smu.measure.read()
testDir = "TestData5"
-- create a directory on the USB drive for the data
file.mkdir(testDir)
fileName = "/usb1/" .. testDir .. "/myTestData.csv"
buffer.save(defbuffer1, fileName)
if file.usbdriveexists() != 0 then
--testDir = "TestData3"
-- Create a directory on the USB drive for the data
--file.mkdir(testDir)
-- Open the file where the data will be stored
--fileName = "/usb1/" .. testDir .. "/myTestData.csv"
fileNumber = file.open(fileName, file.MODE_APPEND)
-- Write header separator to file
file.write(fileNumber,
"\n\n====================================================================\n")
-- Write the string data to a file
