| 2 | Provides a service to retrieve a pointer to the EFI Runtime Services Table.

| 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.
