| 7 | ** Source: test1.c (FreeLibraryAndExitThread) |
| 8 | ** |
| 9 | ** Purpose: Tests the PAL implementation of the FreeLibraryAndExitThread |
| 10 | ** function. FreeLibraryAndExitThread when run will exit the |
| 11 | ** process that it is called within, therefore we create a |
| 12 | ** thread to run the API. Then test for the existance of the |
| 13 | ** thread and access to the library. |
