* DESCRIPTION:
|
| 5 |
|
|
*
|
| 6 |
|
|
* This package is the implementation of the Semaphore Manager.
|
| 7 |
|
|
* This manager utilizes standard Dijkstra counting semaphores to provide
|
| 8 |
|
|
* synchronization and mutual exclusion capabilities.
|
| 9 |
|
|
*
|
| 10 |
|
|
* Directives provided are:
|
| 11 |
|
|
*
|
| 12 |
|
|
* + create a semaphore
|
| 13 |
|
|
* + get an ID of a semaphore
|
| 14 |
|
|
* + delete a semaphore
|
| 15 |
|
|
* + acquire a semaphore
|
| 16 |
|
|
* + release a semaphore
