| 2 | Provides a service to retrieve a pointer to the DXE Services Table. |
| 3 | Only available to DXE module types. |
| 4 | |
| 5 | This library does not contain any functions or macros. It simply exports a global |
| 6 | pointer to the DXE Services Table as defined in the Platform Initialization Driver |
| 7 | Execution Environment Core Interface Specification. The library constructor must |
| 8 | initialize this global pointer to the DX Services Table, so it is available at the |
| 9 | module's entry point. Since there is overhead in looking up the pointer to the DXE |
| 10 | Services Table, only those modules that actually require access to the DXE Services |
| 11 | Table should use this library. This will typically be DXE Drivers that require GCD |
| 12 | or Dispatcher services. |
