| 2 | Provides a service to retrieve a pointer to the EFI Runtime Services Table. |
| 3 | |
| 4 | This library does not contain any functions or macros. It simply exports the |
| 5 | global variable gRT that is a pointer to the EFI Runtime Services Table as defined |
| 6 | in the UEFI Specification. The global variable gRT must be preinitialized to NULL. |
| 7 | The library constructor must set gRT to point at the EFI Runtime Services Table so |
| 8 | it is available at the module's entry point. Since there is overhead in initializing |
| 9 | this global variable, only those modules that actually require access to the EFI |
| 10 | Runtime Services Table should use this library. |
| 11 | Only available to DXE and UEFI module types. |
