15.2 GetVersion() Implementation
The example below shows an example implementation of the
GetVersion() function of the Driver Family Override Protocol. This function returns a UNIT32 value and, in this case, returns a value from a define statement in the UEFI Driver. The manufacturer of a family of controllers is free to select any version value assignment as long as UEFI Drivers that are required to be used over previously released UEFI Drivers have higher values.#include <Uefi.h>
#include <Protocol/DriverFamilyOverride.h>
#define ABC_DRIVER_FAMILY_OVERRIDE_VERSION 0x00050063
