Quoted string function

[OwenD]

It would be helpful if there was a meta function that would correctly return a quoted string for use mainly as part of an echo >> command or where you are passing an object model value as a parameter.
In Delphi there is quotedStr(myString)
I don't know if there's an equivalent C/C++ function that could be easily exposed?
At present you have to concatenate strings and work out how many double quotes to use to get the desired output.

So instead of
echo >>"/sys/lib/led/sb_leds-restore.g" "set global.sb_leds ="^ """"^{global.sb_leds}^""""

We would have
echo >>"/sys/lib/led/sb_leds-restore.g" "set global.sb_leds =" ^ quotedStr({global.sb_leds})
