* 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 Calpont.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
* or equal to the buffer's length argument, length is too small
