17 // API Information: |

19 // Details: |
|
20 // - Adds a new HAL handler for EHalGroupPlatformSpecific2 |
|
21 // - Tries to add handler for an existing group |
|
22 // - Calls the installed handler |
|
23 // - Tests Find API to find the installed handler |
|
24 // - Removes the handler and tries to remove some fixed HAL group |
|
25 // - Tries to find removed handler |
|
26 // - Tries to call removed handler |
