=item B<$setuid = getcellstatus([CELL]);>

Determines whether the local Cache Manager allows SETUID programs to run
or not.  Returns 1 if SETUID programs are allowed for given CELL
(default local).

=item B<$crypt_flg = getcrypt;>

Gets the Cache Manager encryption flag.  This function is supported only
under OpenAFS.

=item B<$volinfo = getvolstats(PATH [, FOLLOW]);>

Returns information about the volume containing PATH.  The return
value is a reference to a hash table containing the values from the C
structure C<VolumeStatus>.  The hash values can be up to five minutes
old, because the Cache Manager polls the File Server for partition
information at that frequency.  The hash table has the following keys

    Blessed         BlocksInUse     InService
    MaxQuota        MinQuota        Motd
    Name            NeedsSalvage    OffMsg
    Online          ParentId        PartBlocksAvail
    PartMaxBlocks   Type            Vid

You can find an example how to print the entire content of the
returned hash reference in the C<examples/v2/cm> directory.

=item B<$ok = setcachesize(NUM);>

Sets the size of the disk cache. NUM is size in 1K byte blocks

=item B<$ok = setcellstatus(SETUID_ALLOWED [,CELL]);>

Enables or disables the local Cache Manager to run SETUID programs for
the given CELL (default local).

=item B<$ok = setcrypt(FLAG);>

Set the Cache Manager encryption flag to FLAG. Valid values are 'on' or
'off'.  This function is supported only under OpenAFS.
