Application Interface for Extended Alias Support

      Disclosed is an application interface for managing extended
network aliases.

      In many Network Operating Systems (NOS), an alias is an
abstraction of a server resource.  That is, an alias name represents
both a resource and the server that contains that resource.  In this
way the location of a particular resource may be easily changed
without extensive administrative changes.  Resources include print
and serial queues, devices, and directories.

      In many NOSs, the server that contains the resource is limited
to a name of eight bytes.  In addition, only directory resource paths
that conformed to the "FAT" file system are allowed.  These
reduced the usefulness and applicability of aliases when using
file systems, such as the OS/2* High-Performance File System (HPFS).

      The following application interface was developed to solve this
problem.  First, the restrictions on server name and directory path
lengths were removed.  Support for the extended character set and
format of file systems such as HPFS was added.  To avoid breaking
older clients who read directly from an alias database, a separate
database was added to contain entries that utilized the extended

      Second, a mechanism was put in place to dynamically move
entries between databases depending on the server or path
characteristics.  For example, if an administrator moved a print
