|
* use of the latest version is strongly recommended.
|
|
*

|
* {!notice This header file contains many obsolete definitions

* (for compatibility with older applications that still ned them).
|
|
* Do not use this file as a reference manual of OSS.

|
* Please check the OSS Programmer's guide for descriptions
