// Function: SearchVolume
//
// Synopsis: Search the volume of the handle passed in and return the
// path(s) of the matching objects relative to the handle.
// See description of FindObject in ofs\fs\fs\objid.cxx or
// win4dwb\ofs\link\alink.doc for SFindObjectOut structure.
//
// Arguments: [hAncestor] -- Handle to volume root or other object on
// volume of interest.
// [oid] -- The object id of the object(s) to search
// for.
// [pResults] -- A buffer, at least sizeof(SFindObjectOut)
// bytes long, to receive the path of the
// found object (or paths of Lineage matches.)
// [usBufLen] -- Length of buffer, in bytes, at [pResults.]
// [cLineage] -- Maximum number of Lineage matches to return.
// May be 0, in which case no search for Lineage
// matches is made if an exact match by
// OBJECTID is found.
//
//
// Returns: STATUS_SUCCESS -- Found exact match.
// STATUS_NO_SUCH_FILE -- No exact match found. May be lineage matches.
// STATUS_FOUND_OUT_OF_SCOPE -- Found exact match but it is not
// in the scope of [hAncestor.]
//
// Signals: None.
//
// Modifies: [pResults]
//
// Algorithm: Call OFS using FSCTL_OFS_LINK_FINDOBJECT
//
// History: 3-Jun-93 BillMo Created.
