* DESCRIPTION:
|

* Converts an OID into a group if directories and a filename.
|
||
*
|
||
* This function takes a 32-bit Object ID (OID). If DLen is 0, then the
|
||
* OID is converted into 3 hierarchical directory names and a filename.
|
||
* If DLen is >0 then the OID is converted into 5 hierarchical directory
|
||
* names and a filename (using the partition and segment as additional
|
||
* input into the filepath. The actual location
|
||
* of the file is <DBRoot>/<DirA>/<DirB>/<DirC>/<FName>, or
|
||
* <DBRoot>/<DirA>/<DirB>/<DirC>/<DirD>/<part#>/<segFName>. The <DBRoot>
|
||
* entry must be pre-pended by the calling application after calling
|
||
* this function. The value for <DBRoot> is stored in the Columnstore.xml
|
||
* configuration file.
|
||
*
|
||
* PARAMETERS:
|
||
* oid INPUT -- The Object Id.
|
||
* partition INPUT -- partition to be included in filepath.

* segment INPUT -- segment to be included in filepath.
|
||
* dmFilePathArgs* INPUT/OUTPUT -- Points to a buffer structure
|

*
|
||
* RETURN:

* return 0 if everything went OK. -1 if an error occured. Two
|
||
* kinds of errors are possible:
|
||
*
|
||
* - a null pointer was passed in
|
||
* - truncation occured.
|
||
*
|
||
* If a null buffer pointer is passed in, a return code
|
||
* of -1 will be returned FOR THAT BUFFER.
|
||
*
|
||
* Truncation can occur if the buffer length specified in
|
||
* dmFilePathArgs is too small.
|
||
*
|
||
* If a buffer's return code is not zero, the appropriate
|
||
* return code in dmfilePathArgs can be examined. If a
|
||
* buffer's return code is be less than zero, the
|
||
* corresponding buffer pointer was NULL. If it is greater
