Provides a service to retrieve a pointer to the DXE Services Table.
|
|
Only available to DXE module types.
|
|
|
|
This library does not contain any functions or macros. It simply exports a global
|
|
pointer to the DXE Services Table as defined in the Platform Initialization Driver
|
|
Execution Environment Core Interface Specification. The library constructor must
|
|
initialize this global pointer to the DX Services Table, so it is available at the
|
|
module's entry point. Since there is overhead in looking up the pointer to the DXE
|
|
Services Table, only those modules that actually require access to the DXE Services
|
|
Table should use this library. This will typically be DXE Drivers that require GCD
|
|
or Dispatcher services.
