Declaration

Source position: dosh.inc line 103

  function DiskSize(drive: Byte) : Int64;

Description

DiskSize returns the total size (in bytes) of a disk. The parameter Drive indicates which disk should be checked. This parameter is 1 for floppy a:, 2 for floppy b:, etc. A value of 0 returns the size of the current drive.

For Unix only: 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 the initialization of the Dos unit, and have been preset to : !!!

'.' for the current drive, '/fd0/.' for the first floppy-drive (Linux only). '/fd1/.' for the second floppy-drive (Linux only). '/' for the first hard disk.

There is room for 1-26 drives. You can add a drive with the AddDisk procedure. These settings can be coded in dos.pp, in the initialization part.

For an example, see DiskFree .

Errors

-1 when a failure occurs, or an invalid drive number is given.
