Module Name:

rpcuuid.hxx

Abstract:
|
|
|
|
We provide a class which is wrapped around UUIDs in this file.
|
|
This class will be used internally by the runtime to deal with
|
|
UUIDs.

Revision History:

Danny Glasser (dannygl) 03-Mar-1992
|
|
Created worker functions for IsNullUuid, CopyUuid, and
|
|
ConvertToString. This is necessary for medium-model
|
|
(i.e. Win16) support, because the Glock C++ translator
|
|
doesn't support far "this" pointers.
|
|
|
|
Danny Glasser (dannygl) 07-Mar-1992
|
|
Same as above for ConvertFromString.
|
|

|
Remove the I_ routines.

Class Description:
|
|
|
|
This class is simply a wrapper around the UUID data structure.
|
|
Doing this isolates the rest of the program from the internal
|
|
representation of UUIDs.
|
|
|
|
Fields:
|
|
|
|
Uuid - Contains the UUID which this class is a wrapper around.

Zero will be returned if the supplied UUID is the same as this
