NOTE: The following lines are 'version 1' style: all names are exported by default. This style is deprecated !!!
use AFS; # import all AFS names use AFS @AFS::CM; # import just the cache manager names
This module provides several functions to communicate with an AFS file server. It is used to check the status of a file server machine. It has functions to administer mount points and quotas. On request it returns the server(s) that house a given file or directory. Any function required must by explicitly listed by the use statement to be exported into the calling package.
Some of these functions have the optional argument FOLLOW. FOLLOW determines which file should be used should PATH be a symbolic link. If FOLLOW be set to 1, then the symbolic link is followed to its target. If FOLLOW is set to 0, then the function applies to the symbolic link itself. If not specified FOLLOW defaults to 1.
In version 2 all functions are exported only on request. The old behavior from version 1 (export by default) is still available for compatibility, but is deprecated.
none
The following functions will be exported into your namespace if you specifically ask that they be imported.
Displays quota information for the volume containing PATH.
Returns 1 if PATH is in AFS.
Returns the volume name for which PATH is a mount point. If PATH is not a mount point or is not in AFS it returns undef and an error code is set.
Creates a given mount point PATH for the VOLUME. If RW (default 0) is set to 1 it creates a read/write mount point otherwise a regular mount point. If CELL (default NULL) is set, the cell indicator appears in the mount point.
Removes a given mount point PATH. If it was not successful it returns 0 and an error code is set.
Sets the QUOTA (maximum possible size) of the read/write volume that contains PATH.
Returns the name of each file server machine housing PATH. If IP (default 0) is set to 1 then IP addresses will be returned instead of hostnames.
