I may have a solution for you.
In revision #4134, I added a trick for opening existing file descriptors, so
that you can watch them.
The trick is the following: use ".XXX" as file name, where XXX is the file
descriptor number.
This trick only works if:
- You use the FOR READ/WRITE syntax.
- You don't use FOR CREATE/APPEND.
- XXX is a valid file descriptor.
- XXX has been opened for reading if you use FOR READ, and for writing if you
use FOR WRITE.
You can close the file, it will not close the file descriptor. But it will
stop the watching operations.
For example:
hFile = Open ".1" For Write
Print #hFile, "hello ";
Close #hFile
Print "world!"
Tell me if it works for you.
