We've used it all over in our lessons, so let's take a look at it. + +As a matter of fact, constructor is the only thing that this library has. + +To understand how this library works take a look at its *.c and *.h files: + +https://github.com/tianocore/edk2/blob/master/MdePkg/Library/UefiBootServicesTableLib/UefiBootServicesTableLib.c +``` +EFI_HANDLE gImageHandle = NULL; +EFI_SYSTEM_TABLE *gST = NULL; +EFI_BOOT_SERVICES *gBS = NULL; + +EFI_STATUS +EFIAPI +UefiBootServicesTableLibConstructor ( + IN EFI_HANDLE ImageHandle, + IN EFI_SYSTEM_TABLE *SystemTable + ) +{ + gImageHandle = ImageHandle; + gST = SystemTable; + gBS = SystemTable->BootServices; + + return EFI_SUCCESS; +} +``` +https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Library/UefiBootServicesTableLib.h: +``` +extern EFI_HANDLE gImageHandle; +extern EFI_SYSTEM_TABLE *gST; +extern EFI_BOOT_SERVICES *gBS; +``` + +So as you can see this library just sets some global variables - shortcuts for the UEFI main parts. As the library constructors execute before the main app code, with this library you can access `gImageHandle`/`gST`/`gBS` anywhere in your app code from the very start. + +# DESTRUCTOR + +Similar we can create another version of a `SimpleLibrary` that would have both constructor and destructor. + +`UefiLessonsPkg/Library/SimpleLibraryWithConstructorAndDestructor/SimpleLibraryWithConstructorAndDestructor.inf`: +``` +[Defines] + INF_VERSION = 1.25 + BASE_NAME = SimpleLibraryWithConstructorAndDestructor + FILE_GUID = 96952c1e-86a6-4700-96b0-e7303ac3f92d + MODULE_TYPE = UEFI_APPLICATION + VERSION_STRING = 1.0 + LIBRARY_CLASS = SimpleLibrary | UEFI_APPLICATION + CONSTRUCTOR = SimpleLibraryConstructor + DESTRUCTOR = SimpleLibraryDestructor <----------- + +[Sources] + SimpleLibraryWithConstructorAndDestructor.c + +[Packages] + MdePkg/MdePkg.dec + UefiLessonsPkg/UefiLessonsPkg.dec +``` +`UefiLessonsPkg/Library/SimpleLibraryWithConstructorAndDestructor/SimpleLibraryWithConstructorAndDestructor.c`: +``` +#include <Library/UefiLib.h> +#include <Library/SimpleLibrary.h> + +UINTN Plus2(UINTN number) { + return number+2; +} + +EFI_STATUS +EFIAPI +SimpleLibraryConstructor( + IN EFI_HANDLE ImageHandle, + IN EFI_SYSTEM_TABLE *SystemTable + ) +{ + Print(L"Hello from library constructor!\n"); + return EFI_SUCCESS; +} + +EFI_STATUS +EFIAPI +SimpleLibraryDestructor( + IN EFI_HANDLE ImageHandle, + IN EFI_SYSTEM_TABLE *SystemTable + ) +{ + Print(L"Hello from library destructor!\n"); + return EFI_SUCCESS; +} +``` + +Don't forget to change the library backend in the `UefiLessonsPkg/UefiLessonsPkg.dsc`: +``` +[LibraryClasses] + ... + #SimpleLibrary|UefiLessonsPkg/Library/SimpleLibrary/SimpleLibrary.inf + #SimpleLibrary|UefiLessonsPkg/Library/SimpleLibraryWithConstructor/SimpleLibraryWithConstructor.inf + SimpleLibrary|UefiLessonsPkg/Library/SimpleLibraryWithConstructorAndDestructor/SimpleLibraryWithConstructorAndDestructor.inf +``` + +Now our app would have print strings both at the beginning and in the end: +``` +FS0:\> SimpleLibraryUser.efi +Hello from library constructor! +5 +Hello from library destructor! +``` + + +As an example of a library with both CONSTRUCTOR and DESTRUCTOR take a look at the https://github.com/tianocore/edk2/blob/master/MdePkg/Library/UefiDebugLibConOut/DebugLibConstructor.c, it uses `CreateEvent` in a constructor, and closes it in a desctrutor with a `CloseEvent`. + + +# `NULL` library + + +As you already know OVMF includes `Shell` app in itself. For its compilation OVMF package DSC file (https://github.com/tianocore/edk2/blob/master/OvmfPkg/OvmfPkgX64.dsc) contains these strings: +``` +[Components] + ... + ShellPkg/Application/Shell/Shell.inf { + <LibraryClasses> + ShellCommandLib|ShellPkg/Library/UefiShellCommandLib/UefiShellCommandLib.inf + NULL|ShellPkg/Library/UefiShellLevel2CommandsLib/UefiShellLevel2CommandsLib.inf + NULL|ShellPkg/Library/UefiShellLevel1CommandsLib/UefiShellLevel1CommandsLib.inf + NULL|ShellPkg/Library/UefiShellLevel3CommandsLib/UefiShellLevel3CommandsLib.inf + NULL|ShellPkg/Library/UefiShellDriver1CommandsLib/UefiShellDriver1CommandsLib.inf + NULL|ShellPkg/Library/UefiShellDebug1CommandsLib/UefiShellDebug1CommandsLib.inf + NULL|ShellPkg/Library/UefiShellInstall1CommandsLib/UefiShellInstall1CommandsLib.inf + NULL|ShellPkg/Library/UefiShellNetwork1CommandsLib/UefiShellNetwork1CommandsLib.inf + ... + HandleParsingLib|ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.inf + PrintLib|MdePkg/Library/BasePrintLib/BasePrintLib.inf + BcfgCommandLib|ShellPkg/Library/UefiShellBcfgCommandLib/UefiShellBcfgCommandLib.inf + + ... + } +``` + +Here you can notice that some of the library classes have `NULL` class. + +`NULL` library classes are conceptually an "anonymous library". It enables one to statically link code into a module even if the module doesn't directly call functions in that library. + +It can be useful if we don't need to call library API in our app, but just need library constructor/destructor functions. + +If you'll take a look at the file https://github.com/tianocore/edk2/blob/master/ShellPkg/Library/UefiShellLevel1CommandsLib/UefiShellLevel1CommandsLib.c you'll see that this module constructor is used to add additional commands to the Shell: +``` +EFI_STATUS +EFIAPI +ShellLevel1CommandsLibConstructor ( + IN EFI_HANDLE ImageHandle, + IN EFI_SYSTEM_TABLE *SystemTable + ) +{ + ... + ShellCommandRegisterCommandName(L"stall", ShellCommandRunStall , ShellCommandGetManFileNameLevel1, 1, L"", FALSE, gShellLevel1HiiHandle, (EFI_STRING_ID)(PcdGet8(PcdShellSupportLevel) < 3 ? 0 : STRING_TOKEN(STR_GET_HELP_STALL) ));
