// Function: GetVolObjForPath,

|
|
// Synopsis: Given an entrypath it returns the volume object which has
|
|
// the exact same entry path on it.
|
|
//
|
|
// Arguments: [pwszEntryPath] -- The Entry Path is given here.
|
|
// [fExactMatch] -- If TRUE, then the volume object's entry path
|
|
// must match pwszEntryPath exactly.
|
|
// [ppwszVolFound] -- The appropriate vol obj name.
|
|
//
|
|
// Returns:
