Application Programming Interface for Managing Disk Space Limits
in IBM OS/2 LAN Server

      Disclosed is a programmatic interface for managing disk space
limits on IBM OS/2* LAN Server machines.

      As Local Area Networks (LANs) grow in size, and as corporations
downsize from mainframes, disk space on server machines is
increasingly becoming a prized commodity.  Consequently, LAN
administrators want the ability to control the way the disk space is
used.  For example, an administrator may want to grant userid JOE
read/write access to a particular directory tree but wants to ensure
that the size of this directory tree does not exceed 35MB of disk
space.  The OS/2 new LAN Server feature that solves this problem is
referred to as "DASD (Direct Access Storage Device) Limits".  To
enable customers to develop their own custom applications that
exploit the DASD Limits feature, we provide an Application
Programming Interface (API).

      The DASD Limit APIs are designed to be remotable so that a LAN
Administrator can perform the desired functions from a remote
workstation.

      There are seven new DASD Limit APIs.  NetDASDCtl allows an
administrator to install or delete limits on a volume managed by
HPFS386.  It also allows an administrator to refresh the usage counts
on a volume with DASD Limits installed.  The NetDASDAdd function
allows the caller to add a limit (maximum) for a specific directory.
The NetDASDDel function removes a disk space limit fr...
