- MDE UEFI library functions and macros\r
+ The UEFI Library provides functions and macros that simplify the development of \r
+ UEFI Drivers and UEFI Applications. These functions and macros help manage EFI \r
+ events, build simple locks utilizing EFI Task Priority Levels (TPLs), install \r
+ EFI Driver Model related protocols, manage Unicode string tables for UEFI Drivers, \r
+ and print messages on the console output and standard error devices.\r
