* CDS - Current Directory Structure
|
|
*
|
|
* CDS items are used bu the internal routines to store cluster numbers and
|
|
* network identifiers for each logical name. The ID field is used dually,
|
|
* both as net ID and for a cluster number for local devices. In the case
|
|
* of local devices, the cluster number will be -1 if there is a potential
|
|
* of the disk being changed or if the path must be recracked.
|
|
*
|
|
* Some pathnames have special preambles, such as
|
|
*
|
|
* \\machane\sharename\...
|
|
* For these pathnames we can't allow ".." processing to back us
|
|
* up into the special front part of the name. The CURDIR_END field
|
|
* holds the address of the seperator character which marks
|
|
* the split between the special preamble and the regular
|
|
* path list; ".." processing isn't allowed to back us up past
|
|
* (i.e., before) CURDIR_END
|
|
* For the root, it points at the leading /. For net
|
|
* assignments it points at the end (nul) of the initial assignment:
|
|
* A:/ \\foo\bar \\foo\bar\blech\bozo
|
|
* ^ ^ ^
