Ok, I worked around it by just repeating to open the file until I get
back a FileStream.
Not that I like the approach, ideas still welcome :-))
Cheers,

Hi,
I'm trying to use the GPIO on the Raspberry Pi.
After I export a GPIO before setting its direction I need to wait
until all Folders and files of the GPIO pin are created.
I try this with:
FileDirectory default fileExists '/fullPathToTheGpio/direction'
This never returns true.
Any hint on how to find out when I can start writing to the file?
I I just wait 3 seconds before writing to the pin for the first time
it works. Subsequent writes work instantly.
Thanks,
Herbert
