| e500088c |
5 | The UEFI Library provides functions and macros that simplify the development of \r |
| 6 | UEFI Drivers and UEFI Applications. These functions and macros help manage EFI \r |
| 7 | events, build simple locks utilizing EFI Task Priority Levels (TPLs), install \r |
| 8 | EFI Driver Model related protocols, manage Unicode string tables for UEFI Drivers, \r |
| 9 | and print messages on the console output and standard error devices.\r |
