EFI_STATUS EFIAPI _DriverUnloadHandler | ( | EFI_HANDLE | ImageHandle | ) |
Unloads an image from memory.
This function is a callback that a driver registers to do cleanup when the UnloadImage boot service function is called.
ImageHandle | The handle to the image to unload. |

EFI_STATUS EFIAPI _ModuleEntryPoint | ( | IN EFI_HANDLE | ImageHandle, | |
IN EFI_SYSTEM_TABLE * | SystemTable | |||
) |
The entry point of PE/COFF Image for a DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver.
This function is the entry point for a DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver. This function must call ProcessLibraryConstructorList() and ProcessModuleEntryPointList(). If the return status from ProcessModuleEntryPointList() is an error status, then ProcessLibraryDestructorList() must be called. The return value from ProcessModuleEntryPointList() is returned. If _gDriverUnloadImageCount is greater than zero, then an unload handler must be registered for this image and the unload handler must invoke ProcessModuleUnloadList(). If _gUefiDriverRevision is not zero and SystemTable->Hdr.Revision is less than _gUefiDriverRevison, then return EFI_INCOMPATIBLE_VERSION.
ImageHandle | The image handle of the DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver. | |
SystemTable | A pointer to the EFI System Table. |
EFI_SUCCESS | The DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver exited normally. | |
EFI_INCOMPATIBLE_VERSION | _gUefiDriverRevision is greater than SystemTable->Hdr.Revision. | |
Other | Return value from ProcessModuleEntryPointList(). |

EFI_STATUS EFIAPI EfiMain | ( | IN EFI_HANDLE | ImageHandle, | |
IN EFI_SYSTEM_TABLE * | SystemTable | |||
) |
Required by the EBC compiler and identical in functionality to _ModuleEntryPoint().
This function is required to call _ModuleEntryPoint() passing in ImageHandle, and SystemTable.
ImageHandle | The image handle of the DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver. | |
SystemTable | A pointer to the EFI System Table. |
EFI_SUCCESS | The DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver exited normally. | |
EFI_INCOMPATIBLE_VERSION | _gUefiDriverRevision is greater than SystemTable->Hdr.Revision. | |
Other | Return value from ProcessModuleEntryPointList(). |
