This file contains the path prefixes as returned by the
|
||
|
|
NetFileEnum2() API.
|
||
|
|
|
||
|
|
The NetFileEnum2() API returns all of the *resources* remotely
|
||
|
|
opened on a particular server. These resources include open
|
||
|
|
files, communication queues, print queues, and named pipes.
|
||
|
|
This file contains the prefixes for the various resource types,
|
||
|
|
plus some useful macros for manipulating the paths returned by
|
||
|
|
NetFileEnum2().
