| | 2 | Provides library functions for common UEFI operations. Only available to DXE\r |
| | 3 | and UEFI module types.\r |
| | 4 | \r |
| | 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 |
