BOOLEAN EFIAPI UserPhysicalPresent | ( | VOID | ) |
This function provides a platform-specific method to detect whether the platform is operating by a physically present user.
Programmatic changing of platform security policy (such as disable Secure Boot, or switch between Standard/Custom Secure Boot mode) MUST NOT be possible during Boot Services or after exiting EFI Boot Services. Only a physically present user is allowed to perform these operations.
NOTE THAT: This function cannot depend on any EFI Variable Service since they are not available when this function is called in AuthenticateVariable driver.
TRUE | The platform is operated by a physically present user. | |
FALSE | The platform is NOT operated by a physically present user. |
References TRUE.
