Method for Managing User's Resource Assignments

      Disclosed is a method for managing a network user's assignments
to network resources.

      In OS/2* LAN Server, the Network Applications folder keeps
track of all the active network assignments of the program objects.
It creates a table of local devices in a shared memory segment which
is used by a program object to check if a local device is being used
by other program objects.

      The access to the shared memory segment is synchronized by a
mutex semaphore created by the Network Applications folder.  If
program A is started which uses X: to connect to a remote resource,
an entry for X: is added to the table in shared memory with in_use
set to TRUE and usecount incremented by one.  If the user starts
program B while program A is still running, and if the program B
needs the same network assignment, it simply updates the entry in the
table by incrementing the usecount field.  If program B is exited
while program A is still running, then the connection to X: will not
be deleted as the usecount field for X: is greater than one.

      If an OS/2 LAN Server user has a logon assignment of X: to the
resource \\REMSRV\ALIAS1 and if one of the user's applications
requires a network assignment of X: to the same resource
\\REMSRV\ALIAS1, then if the user exits the application, X: will be
deleted.

      The problem described above can be solved by adding the logon
assignments to the table in shared mem...
