Integrate with the host platforms filesystem (Linux)

[wimoos]

All,

Has anyone ever tried to integrate VIC with the host platform through the filesystem ? That is, in linux do:

Code: Select all

ln -s /dev/urandom rnd
xvic

and then in VICE

Code: Select all

10 OPEN1,8,0,"RND"
20 GET#1,A$:IFA$=""THENA$=CHR$(0)
30 PRINTASC(A$)
40 IFST=0THEN20
50 CLOSE1

This works. Also the /proc area might be useful.

Unfortunately, I can't get opening a named pipe to work. It makes VICE hang, so that is doesn't respond anymore. Anybody a clue ?

Regards,

Wim.

It probably is opening the file in blocking mode, what does strace tell you?

Hello srowe

Thanks to strace , I now see that VICE opens files with the syscall openat() and does not use the O_ASYNC flag that is needed when addressing a pipe.

Regards,

Wim.

Make a feature request, perhaps

I just tried this by creating the RND symlink in my ~/vic20/ VICE virtual device directory, and running your BASIC program. It works just fine, I get an output of random numbers.
