4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Unloads an image from memory.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function is a callback that a driver registers to do cleanup
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync when the UnloadImage boot service function is called.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param ImageHandle The handle to the image to unload.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @return Status returned by all unload().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // If an UnloadImage() handler is specified, then call it
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // If the driver specific unload handler does not return an error, then call all of the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // library destructors. If the unload handler returned an error, then the driver can not be
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // unloaded, and the library destructors should not be called
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // Return the status from the driver specific unload handler
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The entry point of PE/COFF Image for a DXE Driver, DXE Runtime Driver, DXE SMM
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Driver, or UEFI Driver.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function is the entry point for a DXE Driver, DXE Runtime Driver, DXE SMM Driver,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync or UEFI Driver. This function must call ProcessLibraryConstructorList() and
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ProcessModuleEntryPointList(). If the return status from ProcessModuleEntryPointList()
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync is an error status, then ProcessLibraryDestructorList() must be called. The return
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync value from ProcessModuleEntryPointList() is returned. If _gDriverUnloadImageCount
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync is greater than zero, then an unload handler must be registered for this image
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync and the unload handler must invoke ProcessModuleUnloadList().
