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. + +Copyright (c) 2006 - 2008, Intel Corporation.
