The Diskfree and Disksize functions need a file on the specified drive, since this
|
|
is required for the statfs system call.
|
|
These filenames are set in drivestr[0..26], and have been preset to :
|
|
0 - '.' (default drive - hence current dir is ok.)
|
|
1 - '/fd0/.' (floppy drive 1 - should be adapted to local system )
|
|
2 - '/fd1/.' (floppy drive 2 - should be adapted to local system )
|
|
3 - '/' (C: equivalent of dos is the root partition)
|
|
4..26 (can be set by you're own applications)
|
|
! Use AddDisk() to Add new drives !
|
|
They both return -1 when a failure occurs.
|
|
The drive names are OS specific
