+ 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.
