This library implement library class DxeServiceTableLib.
|
|
It produce EFI_DXE_SERVICE pointer in global variable gDS in library's constructure.
|
|
|
|
A DXE driver can use gDS pointer to access services in EFI_DXE_SERVICE, if this
|
|
DXE driver declare that use DxeServicesTableLib library class and link to this
|
|
library instance.
|
|
|
|
Please attention this library instance can not be used util EFI_SYSTEM_TABLE was
|
|
initialized.
|
|
|
|
This library contains contruct function to retrieve EFI_DXE_SERIVCE, this construct
|
|
function will be invoked in DXE driver's autogen file.
