/*
|
|
first test for posix directory routines for the c64
|
|
kludges:
|
|
- currently uses cbm_open, which conflicts with standard i/o,
|
|
which in turn makes it infact kindof unuseable. this can
|
|
be easily changed however, since the only reason not to use
|
|
open/read was that it currently appends ,u,r to filenames
|
|
- the offset in current dir stream should better be calculated
|
|
from the values returned by "read".
|
|
- the type flag isnt filled in atm.
|
|
- scandir/alphasort/versionsort is missing
|
|
- some bits are currently untested (ie, unused in the testprogram)
