Usage
fileVar = io.output()
fileVar = io.output("newfile")
fileVar
The descriptor of the output file or an error message (if the function fails)
newfile
A file descriptor to assign (or the path of a file to open) as the default output file
Details
The path of the file to open may be absolute or relative to the current working directory.
When accessed from a remote node using the TSP-Link network, this command does not accept a
file descriptor parameter and does not return a value.
If the function fails, an error message is returned.
Example
local fileName = "/usb1/myfile.txt"
if fs.is_file(fileName) then
os.remove(fileName)
print("Removing file")
else
print("Nothing removed")
end
errorqueue.clear()
print("\n*** io.output")
myfile, myfile_err, myfile_errnum = io.open(fileName, "w")
myfile:write("Line 1")
myfile:close()
do
fileHandle = io.output(fileName)
print(fileHandle)
end
io.close(fileHandle)
print(fileHandle)
os.remove(fileName)
Assign the file to be the default output file.
