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